Re: [Libav-user] No metadata in adts container using libavformat API

[Igor Serganov]

Hello Carl, Thank you for your reply. I think now I have realised that I have 2 issues in my scenario: 1. The code attached (metadata.cpp) writes perfectly some static header during mp3 => mp3 transcoding, however if I use ADTS muxer with AAC output stream inside, metadata is not written. 2. Since one of the tags contains start time of the segment, I need to update its value multiple times (as many as I have 10s segments during transcoding) after calling avformat_alloc_output_context2 and avformat_write_header .  That doesn’t work neither for mp3 nor for adts muxer.

metadata.cpp
Description: Binary data

I would appreciate your help on the following issue. I believe you should provide code that can be compiled stand-alone. It seems very unlikely that you found a bug, much more likely that something is missing in your code (assuming it works with ffmpeg, the application).
