Must have been several nights no sleep and desperation. Now, I used current git build and showed similar results, but I researched more and found out what was the issue: It wasn't memory leak that's why valgrind constantly showed that all heaps were freed and no leaks were possible. The problem was that av_decode_video2 and av_interleaved_write_frame both buffer packets for processing/reordering. Thing is the stream is so large that both of these calls were not fast enough to deal with incoming packets so memory usage kept climbing up. I fixed this by using av_write_frame and provided already interleaved stream. So my bad for not noticing that. I have another issue I would like to get some help if possible: Could you please tell me how to correctly switch between files while reading stream. I am recording 1 hour long files from constant stream. Right now I am doing following: avio_open2(&ofmt_ctx->pb, fname, AVIO_FLAG_WRITE, NULL, NULL ); after 1 hour. avio_close(ofmt_ctx->pb); make new file name avio_open2(&ofmt_ctx->pb, new_fname, AVIO_FLAG_WRITE, NULL, NULL ); Is this right? I though of freeing context and reallocating it again, but wanted to avoid extra tasks in reading/writing loop. P.S. Happy holidays everyone.
