• FFmpeg conform DASH to YouTube Live Stream requirements

  4 septembre 2023, par Aniol Pagès

  I'm trying to stream to YouTube using FFmpeg and DASH. I've generated the stream key and I'm successfully sending the generated files to YouTube. However, YouTube refuses the MPD manifest because it has two AdaptationSet (one for video and one for audio), and the documentation specifies that I should use only one for both video and audio

  


  I've tried to use the -adaptation_sets flag unsuccessfully, and also the -map flag.

  


  Here is one of the commands I've tried :
ffmpeg -re -i "/Users/user/Desktop/file.mp4" \        -map 0:v -map 0:a \        -use_template 1 -use_timeline 1 -window_size 5 -min_seg_duration 5000000 \        -f dash dash.mpd

  


  And with the -adaptation_sets flag :
ffmpeg -re -i "/Users/aniolpages/Desktop/2023-09-03 Taller colar filtrar assubtilar.mp4" -map 0 -map 0 -c:a aac -c:v libx264 \ -use_timeline 1 -use_template 1 \ -window_size 5 -adaptation_sets "id=0,streams=v id=1,streams=a" \ -f dash dash.mpd

  


  Has someone been successful to conform the manifest to YouTube requirements ?

  


  Thank you very much !

  


• Why ffmpeg hangs encoding a void audio track ?

  23 août 2023, par SkizZO

  I've googled an entire day experimenting all possible solutions, but noone had worked.
I have 2 HIK dvr (one is prehistoric vith analogic video). I've made a bash script to retrieve X seconds (as input) of the DVR stored videos (it cut seconds if video ends early) ; also record X seconds of Live view (used for saving Motion Alert in Home assistant).

  


  All works well, BUT i have some issues, and the big one is that when the video has no audio, the download hangs at 9.96 seconds for the old device, and 9.97sec for the new (damn !).

  


  Now let's look at the commands and the logs.

  


  Command : this works with cams with audio, but hangs if cam has an audio silent track ?

  


  makejob=$(ffmpeg -fflags +genpts -y -ac 1 -channel_layout mono -rtsp_transport tcp -hide_banner -loglevel info -err_detect ignore_err -i  "rtsp://$user:$dvrpasswd@$dvraddress:554/ISAPI/streaming/tracks/${camnumber}01?starttime=$starttime&endtime=$endTime" -map 0:v -map 0:a? -ar 44100 -filter:a "volume=$volume" -t $seconds -acodec aac -vcodec copy $filepathname)


  


  (A) result Cam with audio : errors too, but works recording both video and audio

  I suppose it's due to the missing timestamps. Note that also when there is no audio, there is an audio track in the video. It hangs when trying to encode that void track.

  


  (i will comment with logs where no audio is recorded, it works with some errors... maybe other useful infos are there)

  


• FFmpegKit : "Operation not permitted" in many android devices [closed]

  26 août 2023, par Mrm

  I'm using FFmpegKit 5.1.LTS in my application. A lot of my users have reported that they cannot edit videos (10%). When I tried to obtain their logs, I noticed that many of them are encountering an 'Operation not permitted' error. My users have granted all the necessary storage permissions (READ_EXTERNAL_STORAGE, WRITE_EXTERNAL_STORAGE).

  


  Here is an example :

  


  User device :

  


  Manufacturer : Sony
  
Model : SOG05
  
ABI : [arm64-v8a, armeabi-v7a, armeabi]
