Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height Conversion failed! I 'll retest with this patch applied and see if it solves the issue. But as things stand without the patch, hardware-based decode+encode pipelines with specific encoders (QSV & VAAPI), as demonstrated, can be very failure prone depending on the input file attributes. The input file used, as reference, is encoded in the yuv444p colorspace, as shown in the ffprobe output. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
