Comment (by oromit): This is caused by the following line: https://github.com/FFmpeg/FFmpeg/blob/5a70e56f2/libavcodec/mpegvideo_enc.c#L1738 which ends up here: https://github.com/FFmpeg/FFmpeg/blob/5a70e56f2/libavutil/frame.c#L331 Which in turn appends the new side data in this function: https://github.com/FFmpeg/FFmpeg/blob/5a70e56f2/libavutil/frame.c#L617 So what is happening here is that inside of the coded_frame, all side data is just endlessly appended, until av_frame_new_side_data eventually runs out of memory to realloc all that side data. A simple fix might be calling av_frame_unref(s->avctx->coded_frame) before av_frame_copy_props in mpegvideo_enc.c. -- Ticket URL: <https://trac.ffmpeg.org/ticket/5799#comment:6> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker _______________________________________________ FFmpeg-trac mailing list FFmpeg-trac@avcodec.org http://ffmpeg.org/mailman/listinfo/ffmpeg-trac
