[FFmpeg-user] FFmpeg does not add meta tags to mp2 files

[andrew]

The most recent git FFmpeg does not add meta tags to mp2 files when
using the native encoder. An example here:

id3v2 2.4.0 tages can be added to such files using Mutagen's mid3v2,
is there something I am missing with FFmpeg and tagging mp2 files?

Thanks,

Andrew

Interesting, because mplayer too can dump it just fine:
$ mplayer -v -dumpstream -dumpfile test.flv 
rtmp://cp258849.live.edgefcs.net/live/SonLife0616@327662
(Audio and video of the dump are out of sync though.)

I personally don't see why this shouldn't work with ffmpeg. *shrug*

You say it "has to". Could you elaborate?

Not if it "has to". You didn't give us examples of what you are doing -
full command lines for the chain of edits - so I can only guess you are
basically using ffmpeg's filters (in the widest sense) to do these
edits.

If so, you can chain your filters to a filterchain or a complex filter.

$ ffmpeg [...] -vf filter1=a=a1:b=b1,filter2=c=c1:d=d1 [...]
$ ffmpeg [...] -filter_complex 
"[0:v][1:v]filter1=...[outv];[0:a]filter2[outa];[outv][2:v]overlay" [...]

Please show us your commands.

Try put -metadata option just after -i option.

$ ffmpeg -i luckynight.wav -metadata artist="Jody Marie Gnant" -c:a mp2 -b:a 
320k test.mp2

Miya, the order of output options does not matter, if they are all
place between the input and the output.

You could have tried your suggestion within 10 seconds[*] to see that
it doesn't help. ;-)

The standard approach to this kind of issue is to use (as close to) losslessly 
encoded intermediate files as possible. I.e. either use a codec designed for 
lossless encoding such as "HuffYUV", or use something like x264 with "lossless" 
settings.

Oh!  Sorry!!

I have believed Stackoverflow's post.

http://stackoverflow.com/questions/11183093/video-metadata-edit-with-ffmpeg 


In my memory, this worked for video file...

OK, my post is incorrect.  I'd like to follow-up how this thread is going...

The stackoverflow post is correct: the -metadata option should be after the
-i options, so it affects the output.

But it does not need to be JUST after the -i option, which is what you
wrote.

The generic syntax is:

ffmpeg [options for input_1] -i input_1 [options for input_2] -i input_2 \
  ... [options for output_1] output_1 [options for output_2] output_2 ...

Why do you add " " around lossless for x264. Is x264 still lossy even
with "lossless" setting?
BTW what is/are it/they?

Then it seems like a regression. With my much newer version, I get the error

You need, afaik, slowmotion on a ‘bad’h264 to get a to be expected resulting.ext
I think you’ll need something like -vf “setpts=(1/)*PTS”

OK now I understand what is wrong with me.  Thanks for your explanation.

I have confirmed that -metadata artist="Jody Marie Gnant" does not affect to 
the output with Moritz-san's sample code.  ffmpeg version is the latest, 
N-73994-g1909a91.

Now I'm curious about why -metadata artist="Jody Marie Gnant" does not affected 
to the output...

Does anyone know why?

It might not even be possible in classic terms with MPEG I/II (or PS)
containers. I think the original poster pointed out that ID3v2 tools
would add such "metadata" to MP2 files as well, but I think that just
happens to work, and is certainly not supported by ffmpeg.

Yes, you can use "-f mp3" to get the tags for the 
output file.
I suspect such files will not conform to some specification.

You can try the input option "-r", unfortunately 
it does not work for many use-cases.

FFmpeg is not very good with h264 timestamps...

Is it possible to choose different protocol handlers at runtime, as it
is with decoders (analog to the choice of "mp3" vs. "mp3float" using
"-c:v" as inpt option)? Or does using librtmp totally disable ffmpeg's
native implementation?

(Indeed, my librtmp doesn't seem to like this URL, shown by trying with
rtmpdump. But I'm not the original poster. ;-))

FFv1 should be superior in (nearly) every regard, for 
example you would need several different x264 libraries 
to support all possible colour spaces and they are not 
supported by Huffyuv at all.

[FFmpeg-user] Help to convert some formats to web suitable. I sould pay for help

[vedran]

Hello guys,

i need somebody to write me commands for converting videos i'm prepared to
pay that. it should be able to process feew different formats and convert
videos to a few most popular formats.. nothing which would not work out of
box in ffmpeg.. and maybe some tweaking about processor usage and quality
but that second part is less important. Anyone interested?


Please send me how much would that cost aprox. I need to convert *most of*
these:

mov (QuickTime Movie)
mp4 (MPEG-4 Video)
mpe (MPEG Video)
mpeg (MPEG Video)
mpeg4 (MPEG-4 Video)
3g2 (Mobile Video)
3gp (Mobile Video)
3gpp (Mobile Video)
asf (Windows Media Video)
avi (AVI Video)



And convert to *most of* these:


   - HTML5, Flash: MP4/H.264, High profile
   - HTML5: WebM
   - HTML5: Ogg
   - Mobile: MP4/H.264, Baseline profile, 480x360, for wide compatibility
   - Mobile: MP4/H.264, Main profile, 1280x720, for newer iOS devices
   (iPhone 4, iPad, Apple TV)
   - Mobile: 3GP/MPEG4, 320x240 and/or 177x144, for non-smartphones*




Important is to support being played in chrome, firefox, ie9 and iphone and
android.. .. at least, most of those with importance of being able to play
on iphones


p.s. i use videojs for video play.

I firstly know that there are containers which can not hold metadata.  It was

If you're willing to do some work I have a script I use that does most
of what you want, happy to let you have it and you could use it as the
'base' for what you're trying to do.

The problem with paying for something like this is frankly you
probably wouldn't want to pay a sensible commercial rate so the
numbers wouldn't make sense.

I believe it works fine.

This looks unrelated: You cannot easily put metadata 
into a program stream but it should be no problem to 
add some id3 data in front of a mp2 file.

[FFmpeg-user] Cropping small portion of input video while rescaling

[Kieran O'Leary]

Hello,

I am working with a 2k full aperture 16mm DPX scan. It has approx 32 pixels of 
the black perforation area of the film on the top and bottom. I am hoping to 
transcode everything to 720/576 v210 as I'm working on a DVD project (I'm going 
to do a lot of work in a NLE after I transcode). I am using 24fps for now as 
the audio was transferred at 24fps as well. I plan on syncing everything up in 
an NLE and then convert both to 25fps.
I've tried the following output but it results in a 720 * 560 output. I'd like 
the black bars to be removed but the output video to be 720*576. I've achieved 
this in the past with Apple compressor's cropping tool.
Also, is there anything else I'm messing up in general? I'm using square pixels 
as opposed to the PAL standard, as I can convert at the DVD authoring stage (I 
hope I'm not making a colossal mistake there as AVID MC 8 seems to just export 
with square pixels anyhow). The output of the 576p video is really lovely. 
ffmpeg resizing is brilliant.

Re: [FFmpeg-user] Cropping small portion of input video while rescaling

[Kieran O'Leary]

Putting the crop filter before the resize in the filter chain produced the 
desired effect. Any other feedback on my command line would be greatly 
appreciated. I can't get inline quoting to work on outlook web app (which I 
have to use today) so I didn't do any quotes. Sorry if this makes things even 
more confusing.

I am confused. What should be the best codec for my usage: FFV1, x264,
Huffyuv, other?
Could you tell me the good options for this codec?

This is a major issue, you may try options like 
the following that may fix it:
-ts abs
-ts mono2abs

-wallclock 0

(And it is of course possible that this issue 
disappears with alsa, I don't know...)

I believe I suggested "-vcodec mpeg2video -mbd 2 -qscale 2" 
and I didn't change my opinion;-)

ffv1 is lossless, mpeg2video is not and x264 is not 
lossless unless you tell it to be.

Both regarding quality and filesize, I would not suggest 
a lossless encoding from your low-quality source, but a 
high-quality lossy encoding.

(x264 of course allows smaller filesizes than mpeg2video 
for the same quality, so you can safely choose it instead.)

Is it possible to choose different protocol handlers at runtime, as it

native implementation?

(Indeed, my librtmp doesn't seem to like this URL, shown by trying with
rtmpdump. But I'm not the original poster. ;-))

Well, my rtmpdump _does_ work. It claims to be v2.4 and I was able to 
get the stream and pipe it to ffmpeg. Inelegant, but it works. Sadly, 
the audio/video is out of sync by about 75ms. Just enough to be annoying.


What can I do to help track down the problem? Is the interest only in 
the native solution (try without librtmp) or ??


Side question: With the sync problem, I've used -itsoffset (and mapping 
of course) in the past to fix sync issues, but that obviously won't help 
if I don't have the streams split _before_ it gets to ffmpeg. Any solution?

Does the same desync exist with FFmpeg?

I would have to get ffmpeg to work to begin with to test that. Should I 
try ffmpeg without librtmp?


It could be the stream source itself for all I know, but I would still 
need to adjust sync someplace along the food chain if so. I was just 
wondering if there was some unexplored option to adjust audio sync in 
this case within ffmpeg.

Re: [FFmpeg-user] Help to convert some formats to web suitable. I sould pay for help

[vedran]

if it helps me i would send you something for sure.. however just give me
those instructions..

i hope you understand what i actually need..

for me it would be great and enough if i just had 5-6 ffmpeg commands that
do this and that is all.. i have another script that would handle when
where and how that starts

[FFmpeg-user] Animated GIF convertion and average frame rate

[Sub Phil]

RE:
https://trac.ffmpeg.org/wiki/Create%20a%20video%20slideshow%20from%20images

To see why some animated GIF are not working in the export of LibreOffice
Impress, I compare thanks to ffprobe.

I noticed that working animated GIF has:
r_frame_rate=20/1
avg_frame_rate=20/1

While non working animated GIF has:
r_frame_rate=100/7
avg_frame_rate=57/4

I try to use ffmpeg to converted the non working gif to the same parameters
as the working one my CLI is


F:\Art>ffmpeg -y -i "feather.gif" -r 20 -s 260x173 "feather conv.gif"
(Console output below)

Now, if I ffprobe the new gif I see:
r_frame_rate=20/1
avg_frame_rate=175/12

How can I now change the avg_frame_rate to 20/1?
I tried to use the framerate option, but didn't work.

F:\Art>ffmpeg -framerate 20/1 -i "feather.gif" -r 20 -s 260x173 "feather
conv.gif"

available on Github right now (https://github.com/Nolski/popcoder/ the
ffmpeg commands reside in editor.py and the process of running all of the
commands is in video.py) but since we are stitching together video, doing
overlays, rendering text, simply throwing them into a filter chain is
harder than you would think and I'm not even sure if it's possible at all.

 I have attempted to re-encode in a lossless format but no matter the
encoding that I try I always seem to get the error "Error while opening
encoder for output stream #0:0 - maybe incorrect parameters such as
bit_rate, rate, width or height".

By changing the encoding I mean I'm just tacking "-c:v ffvhuff" into the
command before the filter.

OK, Let's cut to the chase..how much would you want to pay (and I
ask this having stated earlier you won't be offering commercial
rates).

If you want it done I would suggest that you need to attract someone
willing to do it for the money, therefore you need to tell them what
you're willing to pay.

Asking how much they want isn't going to work in my opinion.

Re: [FFmpeg-user] Help to convert some formats to web suitable. I sould pay for help

[vedran]

look, just say that you know to do it, now and fast, i'm really into that..
i have no doubts that we would agree on that..

i have no clue how much could that cost.. that is why i'm not offering..

on one hand it could be 20 minutes to tweak that and in another case, maybe
somebody would need a day..i don't have feeling about that

[FFmpeg-user] multiple fade out slow down encoding about two to three times

[Tomáš Hnyk]

Hello,
I created initial captions with fade ins and outs like this:

ffmpeg -i in.mov \

It encodes at 5.5 fps if I let it run for five minutes (the video is  
almost two hours)

If I instead do:

ffmpeg -i in.mov \
-i a/01.png -i a/02.png -i a/03.png -i a/04.png -i a/05.png -i a/06.png -i

[tmp7][8:v]overlay=0:0:enable='between(t,8.4,9.4)'[tmp8]; \
[tmp8][9:v]overlay=0:0:enable='between(t,9.6,11.2)'[tmp9]; \
[tmp9]ass=../neposunute.ass[outv]" \
-map [outv] -map a:0 \
-c libx264 -preset slow  -profile:v high -crf 19 \
-strict -2 -c:a aac -b:a 192k \
-f mov -y  out.mov

It encodes in roughly 14 fps. But fade ins and outs occur only at the very  
beginning (in the first 11 seconds), yet the slow down is preserved (I  
also run the compilation for about five minuts). Is this a performance bug?

Tomas

Hello!

I have a Logitech C920 affected by a know-yet-wontfix kernel uvc-video bug[1]. 
Given That I need a relatively recent kernel and it looks like the problematic 
patch in 3.17+ will not be reverted, I am hoping that ffmpeg can somehow help 
me with a workaround.

The problem in short is that while the hardware h264 encoder in the camera 
provides correct PTS values, the kernel driver then throws them away and 
recalculates them incorrectly based on the usb clock or something [2]. I am 
wondering if there is a way to force ffmpeg to discard the (now incorrect) PTS 
again, and assign its own base on the machine clock.

I (blindly at this point) tried various permutations of formats (muxed or raw) 
and the various ffmpeg options of:
-fflags genpts
-copyts
-copytb [0/1]
-map ,

All to no avail. Either the stream stutters[3] (when muxing into matroska or 
mp4) or the stream runs smoothly but about 2x times faster than realtime (when 
using -f h264 )

You need, afaik, slowmotion on a ‘bad’h264 to get a to be expected resulting.ext
I think you’ll need something like -vf “setpts=(1/)*PTS”


What is  in this case...? The camera returns a variable frame 
rate afaik...

What ffmpeg version you are using?
Fade filter can use multiple cores to speed up filtering.
What fps speed you want?

The version is:
ffmpeg version 2.5.7-0ubuntu0.15.04.1 Copyright (c) 2000-2015 the FFmpeg  
developers

  built with gcc 4.9.2 (Ubuntu 4.9.2-10ubuntu13)

All my 4 cores were used to the fullest. I want the same fps as without  
the fade filter in the parts of the video where there is no fading. The  
video is 105 minutes long. Fade ins and outs are all in the first eleven  
seconds. I do not mind if these first eleven seconds are rendered  
super-slowly, but why does the whole encoding process (for the whole  
105-minute-long video) take about 2.5 as long as without the fade filter?

Good luck.

Re: [FFmpeg-user] what program to use to grab device and send to ffserver?

Hi guys,

I’ve had the chance to try out all 16 modes…

I only got video from modes 9 and 12

[decklink @ 0x7f94b081ba00] 9   1920x1080 at 3/1001 fps
[decklink @ 0x7f94b081ba00] 12  1920x1080 at 3/1001 fps 
(interlaced, upper field first)

what is the effective difference between interlaced and non-interlaced, in 
terms of the resulting video file? In terms of streaming, also…?

thank you
Ricardo

I thought the blackmagic device already provided H.264 in hardware, however it 
seems the drivers are seeing rawvideo. Do you know how to get h264 video?

[FFmpeg-user] taking audio and video inputs from different devices

[Ricardo Kleemann]

Hi,

I’m not having much success mixing in audio from the default audio input with 
the video. The video comes out fine but audio is basically inaudible with 
intermittent a little bit of static.

I don’t know if I have the proper settings, I do know that if I don’t use the 
async flag then the video plays back in very fast forward.

the avfoundation “none:1” would be to use the default built-in audio 


$ ffmpeg -f avfoundation -i "none:1" -ac 2 -f decklink -re -i 'UltraStudio Mini 
Recorder@9' -vcodec libx264 -crf 20 -preset veryfast -vf scale=640:360 -async 1
