• Fuji .mov file converted by ffmpeg doesn't play in Windows Media Player [closed]

  30 août 2023, par glipster

  My Fuji X-T3 generates an FHD movie as a .mov with HEVC video and PPM audio. The new Media Player on Windows won't play this (without buying a codec) so I convert it to .mp4 using ffmpeg CLI (ffmpeg -i in.mov out.mp4). The resulting .mp4 file uses AVC video and AAC LC audio. This plays fine in VLC, but will not play in Windows Media Player nor Media Player. I've experimented with various options, but nothing seems to work.
For the original source .mov file, MediaInfo identifies 3 streams :
1stVid : English, 201Mb/s, 1920*1080 (16:9), at 29.970 FPS, HEVC (Main10@L5.2@High)
1stAud : english, 2304 kb/s, 48.0 hKz, 24 bits, 2 channels,PCM (Little/Signed)
1 : QuickTime TC

  


  The Output .mp4 file shows :
1stVid : English 3312kb/s, 1920*1080 (16:9) at 29.970 FPS, AVC (High 10@L4)(CABAC/4 RefFrames)
1stAud : English 132 kb/s, 48.0 kHz, 2 channels, AC LC
1 : QuickTime TC

  


  Using ffmpeg CLI, I tried changing the bitrates for the video and audio, I tried removing the timecode stream, tried a different AAC codec, tried moving the metadata to the front (-movflags faststart), also tried -strict experimental, tried first converting to .mkv (which does work) and then converting to .mp4 (with and without copy). I had hoped one of these might work ; but nothing has worked thus far.

  


  Has anyone else solved this problem ? Any help would be greatly appreciated.

  


• Need help : Discord Player FFMPEG Process Not Terminating Properly - Return Code -9

  26 février 2023, par Goten

  I am encountering an issue with Discord Player's FFMPEG process that is not terminating properly. I receive the following error message :

  


  "INFO discord.player ffmpeg process 10984 has not terminated. Waiting to terminate...
INFO discord.player ffmpeg process 10984 should have terminated with a return code of -9"

  


  I am not sure what this error means or how to fix it. I have attempted to restart my computer and the Discord bot, but the error persists. I have also checked for any updates to Discord and FFMPEG, but there are none available.

  


  This error is preventing me from using Discord bot for streaming the audio, and I would appreciate any assistance in resolving it. If anyone has encountered this issue before or has any suggestions for how to fix it, I would be grateful for your help.

  


  Thank you in advance.

  


  What i am expecting :

  


  I am currently experiencing an issue with my Discord bot, where it is not able to play audio in the voice channel despite being provided with a valid URL. I have attempted to troubleshoot this issue by examining the bot's code and verifying that it is correctly configured to play audio in the voice channel.

  


  Furthermore, I have checked the Discord API documentation and ensured that I am following the appropriate guidelines for playing audio in a voice channel. Additionally, I have verified that the bot has the necessary permissions to join and play audio in the voice channel.

  


  However, despite my efforts, the bot is still unable to play audio in the voice channel. I am expecting the bot to play the audio once the URL is provided, but it does not appear to be functioning correctly.

  


  I would appreciate any assistance in resolving this issue and getting my bot to play audio in the voice channel as intended.

  


• DASH playback for encrypted .webm video files in Shaka Player

  7 mars 2017, par Prabhdeep Singh

  I have been trying to play encrypted .WEBM media files in ShakaPlayer without much success and I am here to seek advise from anybody who had been through this. It would be great if somebody in this awesome developer community can guide me here.

  Round 1 - What I tried (Encoded & Dashed) :

  • Encoded .MP4 file to multiple-streams Video .WEBM (VP9) &
    single-stream Audio .WEBM (Vorbis) files using FFMPEG.
  • Created DASH MANIFEST.MPD file with WEBM_TOOLS/WEBM_DASH_MANIFEST

  Outcome : I am able to play this in Shaka Player without any issues.

  Round 2 - What I tried (Encoded, Encrypted & Dashed) :

  • Encoded .MP4 file to multiple-streams Video .WEBM (VP9) & single-stream Audio .WEBM (Vorbis) files using FFMPEG.

  • Encrypted generated .WEBM files with WEBM_TOOLS/WEBM_CRYPT

  • Created DASH MANIFEST.MPD file with WEBM_TOOLS/WEBM_DASH_MANIFEST

  Outcome : I don’t know how should I play this content in Shaka Player. Where and how should I provide the .key file generated in step 2 above to Shaka Player. I would like to use Clearkeys with CENC on browser. I don’t want to encode to multi-stream .MP4, but only .WEBM.

  Thanks so much !
