From: Jan Sebechlebsky Hello, I've observed several memory leaks in segment muxer in case the failure happens in seg_init (write_header call). I'm sending patchset to fix those. Regards, Jan Jan Sebechlebsky (3): avformat/segment: Check write_header return value

[FFmpeg-devel] [PATCH 3/3] avformat/segment: Use deinit function to deinitialize muxer

From: Jan Sebechlebsky This commit moves all deinitialization of SegmentContext to seg_free_context function and registers this function as .deinit function of segment muxer. This also fixes memory leaks caused by context not being deinitialized when write_header call

[FFmpeg-devel] [PATCH 2/3] avformat/segment: Ensure write_trailer is called

From: Jan Sebechlebsky Ensure that write_trailer is always called after successful write_header operation so underlying muxer is deinitialized. Signed-off-by: Jan Sebechlebsky --- This is a little tricky - we have to ensure that

[FFmpeg-devel] [PATCH v2] avformat/tee: Move to new BSF API

From: Jan Sebechlebsky Signed-off-by: Jan Sebechlebsky --- I've rewritten the patch rapidly. Instead of using recursion it accumulates bitstream filtered packets in fifo buffer and dynamic array is used instead of linked list to store

[FFmpeg-devel] [PATCH] libavutil/fifo: Fix fifo grow step

From: Jan Sebechlebsky Fifo was reallocating always to twice of the requested size. This fixes it to reallocate to requested size, or twice of the original size - whichever is greater. Signed-off-by: Jan Sebechlebsky --- I believe the

[FFmpeg-devel] [PATCH v2 1/2] avformat/tee: Fix TeeSlave.bsfs pointer array size

From: Jan Sebechlebsky TeeSlave.bsfs is array of pointers to AVBitStreamFilterContext, so element size should be really size of a pointer, not size of TeeSlave structure. Signed-off-by: Jan Sebechlebsky --- I've rewritten sizeof as
