  • FFMPEG HLS Multiple audio languages with var_stream_map - EXT-X-MEDIA:TYPE doesn't contain LANGUAGE

    30 janvier 2020, par Moonsurfer_1

    I have a question involving multiple audio languages on HLS with FFMPEG.

    I’m currently using the following command to mux a transport stream with multiple audio languages into an HLS stream with a master playlist :

    ffmpeg -re -i $INPUT_URL -map 0:v -c:v copy -map 0:a -c:a copy -f hls -hls_time 6 -hls_list_size 10 -hls_flags delete_segments+program_date_time -hls_segment_filename "$FULL_OUTPUT_FOLDER/stream_%v_%d.ts" -var_stream_map "v:0,agroup:groupname a:0,agroup:groupname a:1,agroup:groupname a:2,agroup:groupname a:3,agroup:groupname" -master_pl_name master.m3u8 $FULL_OUTPUT_FOLDER/stream-%v.m3u8

    The output of this command looks like this :

    While this does seem to work with VLC, I need the EXT-X-MEDIA:TYPE tag to contain the LANGUAGE property. (the player I’m working with uses it to parse the audio tracks’ language) I can’t figure out how to do that based on the documentation I’ve found.

    Could anyone help me with this ?

    Thanks !

  • tf.contrib.ffmpeg.decode_audio replacement ?

    27 juin 2019, par Imran Paruk

    In the tensorflow docs, it stated that tf.contrib.ffmpeg.decode_audio is depreciated, however it does not state what it’s replacement is...

    THIS FUNCTION IS DEPRECATED. It will be removed after 2018-09-04. Instructions for updating : This will be deleted and should not be used.

    Here is the link : https://www.tensorflow.org/api_docs/python/tf/contrib/ffmpeg/decode_audio
