Where can I find a C/C++ FFmpeg extensive tutorial ?
5 janvier 2013, par fabioI want to use ffmpeg (in its c library form) to split a video in more parts, recompose them and encode the final result. Something basic. But it's very difficult to find documentation or hints about this. Where should I look/ask for advice ?

Concatenate all opus audio in folder and create chapters
7 octobre 2024, par Petrus VermaakI need to join multiple (mp3 or opus) audio in a directory into a single file. I also need to preserve/create each audio as a chapter. The expected outcome is that the output contains the chapter information in the file, so one can easily skip to the desired chapter using vlc player, etc.


I need to do this on Windows and have found a way to join the files, but it does not preserve the chapter information :
cmd type *.opus | FFmpeg -i pipe: -c:a copy all.opus


Can anyone please tell me how to preserve chapters on Windows ? I don't mind using a script as long as you tell me how to create and execute it, seeing that I am a total noob lol


The expected outcome is that it works like an audiobook. I have already seen that both mp3 & opus can have chapters, so I want to do this for all my audiobooks that have multiple files.

Why I can't decode h264 stream ?
23 avril 2015, par Zhe ChenI am now working on decoding h264 stream sent by a device.
The platform I use is Android and the library I use is ffmpeg. Now I have done all the preparation including successfully registering a codec and a
codeccontext
, putAVCDecoderConfigurationRecord
in ’extradata
’ ofcodeccontext
filling with SPS/PPS parameters.However, when I decode packet data using
av_decode_video2
, the returned value is always-1094995529
which means invalid data I found in the source code of ffmpeg. I really have no idea what’s going wrong here.The data stream I am dealing with forms like this :
[0x000167...][0x000168...][0x000161...][0x000161...]......[0x000161...][0x000167...][0x000168...]......
Could anyone please kindly help me with this issue ? It’s driving me crazy right now.
I have tried parsing the
0x61
packet withav_parser_parse2
according to some others’ posts but that didn’t work.
