  • FFMPEG - VP9 - Fail to create DASH manifest file

    18 mars 2019, par Lev Bein

    Can’t create manifest.mpd file with FFMPEG.

    It writes :

    Stream mapping:
    
Stream #0:0 -> #0:0 (copy)
    
Stream #1:0 -> #0:1 (copy)
    
Could not write header for output file #0 (incorrect codec parameters ?): Invalid data found when processing input

    My code to generate manifest is :

    ffmpeg \
    
    -f webm_dash_manifest -live 1 -i video720.hdr \
    
    -f webm_dash_manifest -live 1 -i audio128.hdr \
    
    -map 0 -map 1 -c copy \
    
    -f webm_dash_manifest -y -live 1 -adaptation_sets "id=0,streams=0 id=1,streams=1" \
    
        -chunk_start_index 1 -chunk_duration_ms 2000 -time_shift_buffer_depth 7200 -minimum_update_period 7200 manifest.mpd

    Thanks Shimon

  • WebM live streaming via DASH

    4 juin 2018, par ewack

    I am following the instructions here to try to make WebM live streaming via DASH. My input is from an Axis camera and it is streaming as h264 encoding. I am using node to spin up the ffmpeg processes. I am able to create the .hdr file and the .chk files. The .mpd file is even created but it’s empty and I get an error saying :
