• Ffmpeg RTSP stream with size=N/A bitrate=N/A [closed]

  6 octobre 2024, par Comycos

  When I try to stream a video it seems to work but bitrate and size are N/A frame=  277 fps= 26 q=-1.0 size=N/A time=00:00:11.07 bitrate=N/A speed=1.05x

  


  I run the following command to stream a video to a RTSP server :
ffmpeg -re -stream_loop -1 -i idurre-2024-09-17-12h33m19s.mp4 -c copy -f rtsp -rtsp_transport tcp rtsp://localhost:8554/test

  


  The output ffmpeg is like this :

• FFMPEG - copy the SPECIFED tracks only, ignore all others

  10 janvier 2024, par GDP

  I have some very strange MP4 files that we get regularly for processing created by Wowza. Neither FFMPEG or MEDIAINFO can detect that there are subtitles soft-coded in them, but they ARE there, I can extract them with ccextractor, and when they're played, the captions appear later in the video where the actually start in the timeline.

  


  I've tried every variation of copying with/without re-encoding, but all the answers show how to "omit" the subtitles with -sn such as these :

  


   ffmpeg -i 3078.mp4 -c copy -sn 3078_sn.mp4
 ffmpeg -i 3078.mp4 -c:v libx264 -c:a ac3 -map 0:v:0 -map 0:a:1 3078_sn.mp4
 ffmpeg -i 3078.mp4 -map 0:v:0 -map 0:a:0  -map -0:s -map -0:d  -c copy 3078_sn2.mp4 -y

  The problem seems to be that FFMPEG isn't detecting they're there, and so copies them anyways. My assumption is that they're not stored in the header of the MP4 properly (or however that's done), so get because they're later detect, but weren't omitted when it checked the header (pure guesswork on that).

  


  So, is there a way to copy ONLY the video, regardless of whatEVER tracks may or not be in the file, then do the same for audio, and then merge the two single-track files ?

  


• Why does my ffmpeg audio sound slower and deeper - sample rate mismatch

  4 septembre 2020, par yogesh zinzu

  ok so this is a discord bot to record voice chat
https://hatebin.com/hgjlazacri
Now the bot works perfectly fine but the issue is that the audio sounds a bit deeper and slower than normal.. Why does it happen ? how can I make the audio sound 1:1..
