• How to use ffmpeg to extract WAVE_FORMAT_GSM610 file to WAVE_FORMAT_PCM file

  26 juillet 2017, par xuejianbest

  I have a compressed audio file that is WAVE_FORMAT_GSM610 format.

  Now I want to open it with python wave module. But wave module only support WAVE_FORMAT_PCM file.

  I setup ffmpeg tools. What command can I use to complete this conversion ?

  Or Is there good way to complete the task ?

  Thinks.

• FFMPEG Increment File Metadata dont work on video file (Raspberry OS) [closed]

  16 août 2023, par Fábio Rodrigues

  I want my camera to record 24 to 24h, but i want to have an output video file every 1 hour.

  


  My problem is the filename, its not incrementing for some reason and so this implies that it will constantly rewrite the same file.

  


  : : EDIT
The file always output as "ff-%3d.avi" instead of incrementing "ff-001.avi".
Changing to "ff-%03d.avi" or "ff-%%03d.avi" also dont increment

  


  And for some reason it dont ask if i want to rewrite.
I also notice that changing the output file to jpeg it works well.

  


  


  ffmpeg -stream_loop -1 -framerate 24 -video_size 1920x1080 -t 01:00:00 -i /dev/video0 ./Videos/ff-%3d.avi

  


  


  I believe the command is correct because its working without the incrementing.

  


  I'm running this on a raspberry pi 4 with raspberry OS bulleye 11.

  


  Apreciate your help

  


• Convert MP4 File to M3U8(only m3u8 file No ts file) [closed]

  28 février 2024, par Ayan Ansari

  I'm a beginner working on a content streaming app (like Netflix) where i want to add feature of quality control of the content (like switch to 480p, 720p, 1080p etc). I'm using Exoplayer for video player and the app is almost ready. But the problem i've been facing is that all the files are either mp4, mkv etc file but i need m3u8 file. So I tried converting video using FFmpeg tools which worked but it gives me LOTS OF TS file which i need to upload along with the m3u8 file. After doing some more research i was able to reduce it to 1 m3u8 and 1 TS file. Is it possible to Create only 1 m3u8 file no TS file ? Here are what i've tried.

  


  ffmpeg -i input.mp4 -c:a aac -strict -2 -c:v libx264 -preset ultrafast -crf 28 -maxrate 2M -bufsize 4M
-hls_time 6 -hls_playlist_type vod -hls_flags single_file -f hls output.m3u8


  


  I also thought i will upload all the video in different quality manually, but as a broke 17 Y/O teenager, noobie who don't know how to use AWS or cloud Servers and also AWS or Google Cloud doesn't accept Indian Debit Card(Rupay) for free trial.
Please also suggest some where i can store these data for free i guess( i don't care about where i upload, i just need the link which i can put in my database.)
Thank You :)
