Re: [FFmpeg-user] Error: [AVFilterGraph @ 0xabe1cc0] No such filter: 'ass'
If you compile ffmpeg, you may add libass to the binary. See this page on how to compile: https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu Kind regards, Daniel 2016-01-12 12:07 skrev jun saturay: Thanks Moritz.

If you had passed any arguments to ./configure when building, they would be shown here, approximately as: > configuration: --enable-libass I believe you're still using the same ffmpeg binary as before.

Re: [FFmpeg-user] MPEG1/2 does not support 3/1 fps
Do you have a suggestion on what I should do instead? I simply want to stream my web cam to another computer and I have no clue on which encoder I should use.

Indeed, it tries to encode to mpeg1video with a frame rate of 3, which ffmpeg only supports if it is forced to so.

[FFmpeg-user] MPEG1/2 does not support 3/1 fps
I want to stream my web cam /dev/video0 using ffmpeg and ffserver. I have compiled the latest sources by looking at this page: https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu Now I try to start ffserver by looking at this page: https://trac.ffmpeg.org/wiki/ffserver I have created /etc/ffserver.conf with this content: http://ffmpeg.org/sample.html And I start ffserver with: ffserver -d -f /etc/ffserver.conf Then I start ffmpeg with: ffmpeg -f v4l2 -s 320x240 -r 25 -i /dev/video0 -f alsa -ac 2 -i hw:1,0 http://localhost:8090/feed1.ffm But I get the errors: MPEG1/2 does not support 3/1 fps Error while opening encoder for output stream #0:1 - maybe incorrect parameters such as bit_rate, rate, width or height My web cam is a "Creative Live! Cam Sync HD" with 1280x720 resolution and I have Ubuntu Linux. Kind regards, Daniel ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user
