Again, Thanks for your input -- never said the code was bug free or even not buggy -- but I do know the free of all the context listed are being called and other than avformat_free_context() which has no way to check it worked (not sure way it was written like that) are validated.
code is here https://github.com/wkeeling63/racecam Please let me know if you have any ideas Thanks ________________________________ From: Libav-user <[email protected]> on behalf of Paul B Mahol <[email protected]> Sent: Wednesday, March 3, 2021 1:28 PM To: This list is about using libavcodec, libavformat, libavutil, libavdevice and libavfilter. <[email protected]> Subject: Re: [Libav-user] Reuse of format context after free and reallocate?

If you are on Linux, using it is very easy. yes, I am free the all contexts before reallocation but I cannot find a way to for the FLVContext/Muxer to be freed/reinitialized thru the API. I am doing the following: avcodec_free_context() of all streams video and audio avformat_free_context() avio_close() If you really do all this than that error would never happen. ________________________________ From: Libav-user <[email protected]<mailto:[email protected]>> on behalf of Paul B Mahol <[email protected]<mailto:[email protected]>> Sent: Wednesday, March 3, 2021 5:54 AM To: This list is about using libavcodec, libavformat, libavutil, libavdevice and libavfilter. <[email protected]<mailto:[email protected]>> Subject: Re: [Libav-user] Reuse of format context after free and reallocate?

Looks like the avformat_write_header()/avformat_init_output uses the state of the muxer at the last run even if the AVFormatContext has been freed and reallocated. So how do I get the FLVContext to be initlized as if a fresh run. Or how do I free the old FLVContext so when avformat_write_header() initlizes the priv_data it is fresh. ________________________________ From: Libav-user <[email protected]<mailto:[email protected]>> on behalf of william keeling <[email protected]<mailto:[email protected]>> Sent: Monday, March 1, 2021 2:32 PM To: [email protected]<mailto:[email protected]> <[email protected]<mailto:[email protected]>> Subject: [Libav-user] Reuse of format context after free and reallocate? I have a program the creates flash format stream and is work the first time thru but when I process the second stream, I get DTS/PTS non monotonically errors. After each stream I free and reallocate all contexts: avcodec_free_context() of all streams video and audio avformat_free_context() avio_close() What am I missing so the format context can be reallocate and used? Looks like to be real bug to me.
