Complete, uncut console output missing but you cannot
mux rawvideo in a transport stream.

Hi Everybody,
i am on a windows machine, attached to it a decklink SDI Card, where i get a
uyvy422(TV) signal over dshow. To see where latency happens, i wanted to stream
raw without encoding this feed. I used the command:
ffmpeg -f dshow -i video="Blackmagic WDM Capture" -r 25 -codec copy -a
Is it possible to right-justify text on a video at a certain coordinate
using drawtext? I see no documentation on this.
Thanks in advance for any help,
Les

Maybe you only installed the library, but not the
headers? ("-devel" or "-dev")
You need "/usr/include/vpx/vpx_decoder.h" or

I should add here that while ffv1 is a complicated
codec, r10k (like v210) is so trivial that you can

This is unfortunately not possible with current
FFmpeg (although it is technically possible and
not particularly difficult).

Hi,
I'm trying to convert aac latm to aac raw so that i can copy the audio to a
usable format without converting. From reading it seems that there might be
a -bsf filter that may be able to handle this for me but i cannot find
anything that may work. Is there a good way to do this in one command s
anyone?

Why do you want to "go back" to r10k?

With FFplay? Or did you test another application?

This code works great:

Ok Carl, so your fix does work! Wonderful! I can now use FFPlay to view the

Hi folks,
I'm sure this won't be of interest to a sufficiently large audience to warrant
any changes, but just for the record - no, Blackmagic disk recorders won't play
ProRes files encoded with ffmpeg.
I used a command similar to:

Please test "-video_track_timescale" (and
remove -r and the filter).
