  • What are all the codecs and formats not supported by FFmpeg ?

    4 mars 2020, par Alexander Swann

    We are building a service where we do not know what format/codec a video uploaded by a user is in. Due to the nature of the application, we expect input video formats to be very fragmented, diverse and niche. We are currently using FFmpeg to transcode input formats to a consistent output (e.g. mp4).

    Due to the above scenario, I would like to establish a general list of what formats and codecs are not currently supported by FFmpeg. This is so I can research other open source video transcoding tools which I can utilise to fill in the gaps and allow our service to be more reliable for the user.

    Are there resources online that can help at least get a general idea of what might not be supported by FFmpeg ?

  • Is it possible to stream multi framerate videos using MPEG-DASH ?

    9 août 2018, par Suresh Murali

    I transcoded a mp4 video to several framerates like 5FPS, 10FPS .. 30FPS and used MP4Box to segment them to play in DASH IF player.

    FFMPEG Command to generate multi framerate videos with same resolution :

    ffmpeg -i fball.mp4 -f mp4 -vcodec libx264 -profile:v high -vf scale=1280 :-1 -b:v 2000k -minrate 2000k -maxrate 2000k -bufsize 2000k -nal-hrd cbr -g 120 -keyint_min 120 -r 60.0 -flags +cgop -sc_threshold 0 -pix_fmt yuv420p -threads 0 -x264opts keyint=120:min-keyint=120:sps-id=1 -an -y fball_720p_60fps.mp4

    ffmpeg -i fball.mp4 -f mp4 -vcodec libx264 -profile:v high -vf scale=1280 :-1 -b:v 1000k -minrate 1000k -maxrate 1000k -bufsize 1000k -nal-hrd cbr -g 60 -keyint_min 60 -r 30.0 -flags +cgop -sc_threshold 0 -pix_fmt yuv420p -threads 0 -x264opts keyint=60:min-keyint=60:sps-id=1 -an -y fball_720p_30fps.mp4

    FFMPEG command to extract audio :

    ffmpeg -i fball.mp4 -acodec aac -b:a 128k -vn -strict -2 -y fball_audio.mp4

    MP4Box command for segmentation :

    MP4Box -frag 2000 -dash 2000 -rap -base-url ./segments/ -profile main -segment-name /segments/%s_ -out dash/fball_dash.mpd fball_720p_24fps.mp4 fball_720p_30fps.mp4 fball_720p_60fps.mp4 fball_audio.mp4

    1. Segment Duration : 2 seconds

    2. GOP length : segment duration x FPS of video

    3. Resolution : 720p for all videos

    Result is VIDEO DECODE error or stalls while switching framerate.

    Am I making any mistake while transcoding ?
    Is it possible to stream Multi frame rate videos using MPEG DASH ?
