That is very interesting about Opus's sample rate! For anyone else reading: Opus supports several input sample rates, but the output of a decoder is fixed at 48khz. The sample rate in the header is an informational only reference to the input sample rate. Anyway, your patch does solve my problem. I was also able to reproduce Juan Navarro's issue with OGG/WEBM. These files played in ffplay, but not in VLC, which reported a corrupted opus header. The opus_default_extradata datastructure is 30 bytes long. I modified your patch to only copy 19 bytes, which is the size of a standard opus header. This seemed to resolve the issue and I was able to playback the OGG/WEBM files in VLC. It might be a good idea to change the original datastructure to 19 bytes, but that datastructure is also shared by libavformat/mpegts.c and I don't know if that will add any issues. Thanks for your help, I hope we can get this patch merged into the next release. I changed my email client to send plain-text. I hope that fixes any quoting issues. _______________________________________________ Libav-user mailing list [email protected] https://ffmpeg.org/mailman/listinfo/libav-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
