[FFmpeg-devel] Vibrating and shocking of video's frame

[chengmo]

Hi All: 

  Do someone encountered this situation like the attach showed ?

  If so ,could you give some tips about it ?

  What's the problem could it be ?

 

  I gave the theme about this as follow:

 

  I was used ffmpeg AVIOContext from other source. 

  There were 2 AVIOContexts, one is input, another is output. 

  The media data included by our private protocols, let's call it as
"inpkt".

  When I got the packets and take off the header of the packet,
rewrite the data from "inpkt" to "outpkt" which is AVIOConetext as well.

 

  The "outpkt" we used to send out to browser (Html 5's video tag)
packed in another protocols. The data actually was from "inpkt" without
protocols headers.

 

  It worked ok most of time. It will vibrate in some time.Is there
any size limited for the attachment ? I got the video of the phemon about
the frame shake, it 's supposed to larger as the attachment.

The output of ffmpeg was ok and there was no warning or error information
with default loglevel.

  

  I have no idea about this at all. 

  Could someone give me some suggestions or issue what was it could
be ? 

 

Thanks.

[FFmpeg-devel] The patch fixed the cases of encounter mdat/trak without "moov" or "root"

[chengmo]

Hi All:

I found the patch 'Reimar Döffinger' reimar.doeffin...@gmx.de
  did for ffmpeg in 2012

The url is here:

https://ffmpeg.org/pipermail/ffmpeg-cvslog/2012-March/048841.html

 

the problem about “MOV: bail out to toplevel when encountering a trak
or mdat chunk.”

 

The patch fixed the cases of encounter mdat/trak without “moov” or “root”

Now I use -movflags
“frag_keyframe+empty_moov+default_base_moof+separate_moof”

It will encounter “moof” atom, the fragment including the pairs of moof and
mdat atoms.

 

Should it treated like the way to moov  ? 

Is there could be a mistake so far ? 

I didn’t found it fixed.
