I believe you are using an invalid pixel format value Run the following command to get list of pix_formats
> ffmpeg -pix_fmts From documentation: -pix_fmts: Set pixel format. Use -pix_fmts to show all the supported pixel formats. If the selected pixel format can not be selected, ffmpeg will print a warning and select the best pixel format supported by the encoder. If pix_fmt is prefixed by a +, ffmpeg will exit with an error if the requested pixel format can not be selected, and automatic conversions inside filtergraphs are disabled. If pix_fmt is a single +, ffmpeg selects the same pixel format as the input (or graph output) and automatic conversions are disabled. https://www.ffmpeg.org/ffmpeg-all.html#Advanced-Video-options H264 encoding guide... https://trac.ffmpeg.org/wiki/Encode/H.264 FFMpeg hardware acceleration guide https://trac.ffmpeg.org/wiki/HWAccelIntro Google is your friend ;) _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
