I'm trying to transcode an MPEG4 avi to MP4 with VAAPI, but I'm getting an error:
Impossible to convert between the formats supported by the filter 'Parsed_null_0' and the filter 'auto_scaler_0' Error reinitializing filters! Failed to inject frame into filter network: Function not implemented The failing command is: ffmpeg -hwaccel vaapi -vaapi_device /dev/dri/renderD128 -hwaccel_output_format vaapi -i test.avi -c:v h264_vaapi out.mp4 Other combinations work just fine, like hardware decoding that same video: ffmpeg -hwaccel vaapi -vaapi_device /dev/dri/renderD128 -i test.avi -c:v libx264 out.mp4 Hardware transcoding an MPEG2 input video works fine as well: ffmpeg -hwaccel vaapi -vaapi_device /dev/dri/renderD128 -hwaccel_output_format vaapi -i test.mpg -c:v h264_vaapi out.mp4 Hardware transcoding an H264 video works, too: ffmpeg -hwaccel vaapi -vaapi_device /dev/dri/renderD128 -hwaccel_output_format vaapi -i test.mp4 -c:v h264_vaapi out.mp4 How should I go about debugging this further? _______________________________________________ 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".
