Hello
When I run following command against file in
http://filebin.ca/2z88Rc4fcYbB/videos.tar then output timing is corrupted -
result is like 1 FPS.
ffmpeg -y -i a.mp4 -filter_complex "
nullsrc=size=320x240 [bg];
[0:v] scale=320x240 [main];
[bg][main] overlay=shortest=1" \
-c:v libx264 -pre
Even simpler example to reproduce the problem using just one file from the
referenced tarball:
ffmpeg -y -i b.webm -filter_complex "
color=color=black:size=320x240 [bg];
[0:v] setpts=PTS-STARTPTS,
scale=320x240:force_original_aspect_ratio=decrease [main];
[bg][main] overlay=x=160-overlay_w/2
Hello
I have two videos where one of them changes it resolution (rotation) twice.
I would like to join them side by side. I've used following command:
ffmpeg -y -i a.webm -i b.webm -filter_complex "
color=color=black:size=640x240 [base];
[0:v] setpts=PTS-STARTPTS,
scale=320x240:force_original

Dear All,
Would like to know what is the best way/parameter to force key frame
interval. I would need 2*FPS
I'm feeding FFmpeg's stdout with raw images at fps 25.
So far i have the following command:
ffmpeg -y -loglevel info -f lavfi -i aevalsrc=0 -f rawvideo -pix_fmt
rgb24 -video_size 1280x72

I am not maintainer of mov.c and therefore cannot answer but
the only way to find out is to send a (clean) patch made with

Thanks for the clarification!
So would a patch be accepted that implements readin

(This is not related to your issue, just to FFmpeg configuration in general)
The option --enable-vdpau has no effect, that's why it is not
listed when you run ./configure --help.

Using x264 10bit encoding always (!) means better
quality for a given bitrate, even for 8bit input but many
video players may not be able to playback 10bit h264.
