  • FFMPEG php HLS and DASH conversion

    21 juillet 2020, par Angus Simons

    I'm using this repo https://github.com/aminyazdanpanah/PHP-FFmpeg-video-streaming to encode video in hls and then reproduce on the front end.

    


    After creating all the hls segments correctly the php script fail to execute the command below.
The command getting error is the next one :

    


    '/usr/bin/ffmpeg' '-y' '-i' 'source.mp4' '-c:v' 'libx264' '-c:a' 'aac' '-bf' '1' '-keyint_min' '25' '-g' '250' '-sc_threshold' '40' '-use_timeline' '1' '-use_template' '1' '-init_seg_name' 'dash_init_$RepresentationID$.$ext$' '-media_seg_name' 'dash_chunk_$RepresentationID$_$Number%05d$.$ext$' '-seg_duration' '10' '-hls_playlist' '0' '-f' 'dash' '-adaptation_sets' 'id=0,streams=v id=1,streams=a' '-map' '0' '-s:v:0' '256x144' '-b:v:0' '830k' '-map' '0' '-s:v:1' '426x240' '-b:v:1' '969k' '-map' '0' '-s:v:2' '640x360' '-b:v:2' '1162k' '-map' '0' '-s:v:3' '854x480' '-b:v:3' '1453k' '-map' '0' '-s:v:4' '1280x720' '-b:v:4' '1938k' '-map' '0' '-s:v:5' '1920x1080' '-b:v:5' '2907k' '-strict' '-2' '-threads' '12' 'dash.mpd'


    


    Here there is the error printed executing the command with CLI :

  • ffmpeg filter_complex concat never completes

    10 juillet 2020, par seawolf

    I am trying to concatenate mp4 files into a single file. I am attempting to use the concat filter directly for reasons independent from this question (so -i list.txt is not a valid solution). All video files in question are between 4 and 20 minutes in length.

    


    What I am executing :

    


    % ffmpeg -i f01.mp4 -i f02.mp4 -filter_complex "[0:v][0:a][1:v][1:a]concat=n=2:v=1:a=1[v][a]" -map "[v]" -map "[a]" output.mp4


    


    This is my understanding of the form of this command from references such as FFmpeg Filters Documentation : concat and Concatenate Videos Together Using FFMPEG !.

    


    What happens :

    


    ffmpeg gives a lot of output as it checks the metadata for each stream and then begins processing. After a short duration (several seconds to a minute or so, seems to be prortional to the duration of the first video) I start seeing messages like this :

    


    More than 1000 frames duplicated
More than 10000 frames duplicated     512kB time=00:00:00.12 bitrate=32771.0kbits/s dup=33365 drop=0 speed=0.00449x
More than 100000 frames duplicated   1280kB time=00:00:00.17 bitrate=61442.1kbits/s dup=66730 drop=0 speed=0.00272x


    


    ... and then the process never completes. If I leave my computer running for 24 hours, ffmpeg is still using max available CPU (200-300%). The output file is 48 bytes in length.

    


    Note : the inputs are only a few minutes each, so individually re-encoding the inputs would take only a few minutes each.

    


    Note : if I change the command to use f01.mp4 for both source 0 and source 1, the command completes as expected in under 5 minutes :

    


    % # example that works:
% # note, however, that this just repeats the same source twice
% ffmpeg -i f01.mp4 -i f01.mp4 -filter_complex "[0:v][0:a][1:v][1:a]concat=n=2:v=1:a=1[v][a]" -map "[v]" -map "[a]" output.mp4


    


    Full output :

    


    Here is the complete output of a run in case it's helpful :

    


    % ffmpeg -i f01.mp4 -i f02.mp4 -filter_complex "[0:v][0:a][1:v][1:a]concat=n=2:v=1:a=1[v][a]" -map "[v]" -map "[a]" output.mp4

  • react-native-ffmpeg Unrecognized option 'preset'

    8 avril 2021, par Tommy Khumarga

    Below is my ffmpeg command :

    


    -y -i vidInput.mp4 -vcodec mpeg4 -b:v 1000k -b:a 48000 -preset ultrafast vidOutput.mp4

    


    And the result is :

    


    [Mon Jul 06 2020 20:42:08.171]  LOG      Unrecognized option 'preset'.
[Mon Jul 06 2020 20:42:08.172]  LOG      Error splitting the argument list:
[Mon Jul 06 2020 20:42:08.174]  LOG      Option not found


    


    Need advice...
