Hi,
I use ffmpeg-3.2.10, which fail to get correct frame rate by using following
command:
ffprobe -show_format -show_streams -select_streams v wmv-file
wmv-file can downloaded from the following link:

Hi,
I am starting to experience Circular buffer overrun errors. This errors are
more frequent than before. The only change that I made was to add more ffmpeg
instances (from 24 to 30/35). All instances are on a nvidia M2000 card. From
man and other google sources I understood this error usually
Hi,
try to play around with kernel parameters and increase values for:
net.ipv4.udp_rmem_min
net.ipv4.udp_mem
net.core.rmem_default
net.core.rmem_max
net.core.netdev_max_backlog
net.core.netdev_budget
also check interface Ring parameters:
ethtool -g [interface]
and increase RX and TX
I do a screencast with ffmpeg. The call looks like
ffmpeg -f x11grab -video_size 800x600 -framerate 25 -i :2 -c:v libx264
-pix_fmt yuv420p -preset ultrafast test.mp4
The screencast is stopped by a SIGTERM (15) signal to the
ffmpeg process. In most cases, this works fine.
Occasionally, the ffmpeg

Could anyone tell me why I get slightly different audio durations reported from
the following two commands:
ffprobe -show_streams x.m4a
ffprobe -select_streams a:0 -show_entries format=duration x.m4a
In this case the difference is only 8.023991 vs 8.024000, but it doesn't give
me confidence

Could easily be rounding error depending on how the number is being

So the two *should* be the same, right?
Are you saying they're running the same underlying code the difference is just
in the formatting to the user?
Many thanks.

No, only that with such a small difference (0.000,009) so it's more likely a
formatting error

Hello,
How do I compile ffmpeg so that ffplay can use /dev/fb0 for playback?
./configure --arch=armel --target-os=linux --enable-gpl --enable-omx

It appears that the version of ffplay from the repository can use /dev/fb0

Thank you for the help! I described poorly my problem. What I wanted to ask
was how to download the subtitles text file. When downloaded with IDM,
there was a .TXT file but a VTT in fact.
With ffmpeg I can't download this subtitles file, or I didn't find a way.
If the file exists, how could I get i
Hello Ned,
I know a fair amount about certain audio codecs and audio file container
formats, especially MP3 (the codec and the container and ID3 metadata)
and AAC (codec) and M4A/MP4 (the container and ill-defined metadata
standard).
As I have discussed in at least one other email to this li
