  • ffmpeg : unable to use hardware encoder h264_rkmpp with software decoded ATSC OTA transmission

    20 août 2020, par Brad Bruggemann

    When attempting to hardware encode to h264 using the Rockchip MPP encoder h264_rkmpp from an ATSC source, FFMPEG errors out with :

    


    "Impossible to convert between the formats supported by the filter 'Parsed_null_0' and the filter 'auto_scaler_0'"

    


    The sample file used in this example can be downloaded here : https://transfer.sh/BRMej/out.ts

    


    The full command used and resulting output is as follows :

    


    $ ffmpeg -loglevel 48 -c:v mpeg2video -f mpegts -i out.ts -f mp4 -c:v h264_rkmpp -c:a libfdk_aac -preset ultrafast -mbd rd -copyinkf -flags +ilme+ildct -fflags +genpts out.mp4 -y

  • ffmpeg convert audio to ogg and keep album cover

    29 octobre 2020, par Izaya

    If I convert an audio file with an album cover thank's to :

    


    ffmpeg -i sample1.flac -ar 48000 -vn -c:a libvorbis -b:a 320k sample1.ogg


    


    My sample1.ogg file doesn't have any album cover. Is there a way to ask explicitly to ffmpeg to keep the cover ?
