[ffmpeg] : programmatically determine output format when ripping audio from video files
8 août 2018, par fastilyI have some assorted video files (e.g. mkv, webm, mp4, mts) with various codecs (aac, opus, vorbis) that I’d like to extract the audio from. Does ffmpeg offer a way to intelligently determine the correct output format to use ?
Up until now, I’ve been using ffprobe + sed to achieve this result, but it feels sloppy/verbose. Is there a best practice or am I out of luck ?
Thanks in advance

Issues with ffmpeg2theora- Please port your application to avcodec_decode_audio4()
8 août 2016, par sudheerpaturiI am using the latest versions of ffmpeg and ffmpeg2theora for windows. I try to convert an mp4 file(with audio) to an ogv file using this command on terminal
ffmpeg2theora.exe -v 10 input_file_name.mp4
Then its giving out this error.
Image for the OutputI am totally new to using this tool. From my investigation I found that this is because of the new versions. This problem doesn’t exist with the old versions.
Is there any way to get rid of this issue ?
Thanks in advance.

While transcoding to mpegts ffmpeg creates the first frame after 1.48 seconds delay
15 mars 2018, par Biraj B ChoudhuryI have transcoded a file to mpegts using the following command
./ffmpeg -y -i big_buck_bunny_720p_5mb.mp4 -vcodec libx264 -x264opts "keyint=48:min-keyint=48:no_scenecut" -r 23.976 -c:a copy -f mpegts test.mpegts
When I run ffprobe on it -
./ffprobe -i test.mpegts -select_streams v -show_frames -of csv
I see that the first frame starts at 1.48 seconds why is this so ?

The first frame is at 0.000 when the output is mp4 so this is something particular to mpegts.
