• Syntax error : "(" unexpected — with !(*.sh) in bash script

  3 octobre 2016, par Jmv Jmv

  Regards,

  I want to run a sh file :

  #!/bin/bash
  
  for f in !(*.sh); do ffmpeg -i "$f" -vf yadif=0:-1 -threads 0 -c:v libx264 -pix_fmt yuv420p -r 29.97 -b:v 3000k -s 1280x720 -preset:v slow -profile:v Main -level 3.1 -bf 2 -movflags faststart /mnt/media/out-mp4/"${f%.mxf}.mp4"; rm $f; done

  However I get the following error :

  2: task1.sh: Syntax error: "(" unexpected

  If I try directly on the command line it works perfectly.

  the path and permissions are already reviewed

  Any idea what might be happening ?

  Thank you a lot

• ffmpeg stops randomly with "No more output streams to write to, finishing" when reading rtsp stream [on hold]

  7 juin 2016, par ImagineDragon

  Basically I am running the following ffmpeg command to read an h264 rtsp stream using hls muxer, under Ubuntu 14.04 64bit with i7 CPU and 8GB memory :

  The problem is that ffmpeg exits randomly after 5 to 20 minutes. The RTSP is a live stream so stopping every 5 minute is really not acceptable. In the ffmpeg log I can’t see any noticeable error except "No more output streams to write to, finishing." near the end. Can someone shed some light upon this ? How can I make ffmpeg run without stopping ? Thanks

• Streaming H.264 over UDP using FFmpeg, and "dimensions not set" error

  3 septembre 2015, par Baris Demiray

  I’m trying to stream H.264 over UDP with no luck so far. Here is a minimal code that you can reproduce the problem.

  To compile,

  g++ -o test -lavcodec -lavformat -lavutil test.cpp

  Extra information, I start ffplay as follows. Currently it’s of no use.

  ffplay -i udp://127.0.0.1:8554/live.sdp

  For those who has even more time to spare on my problem, when I change m_output to rtsp://127.0.0.1:8554/live.sdp, and ffplay command to ffplay -rtsp_flags listen -i rtsp://127.0.0.1:8554/live.sdp I get the error,

  Am I naive to expect that streaming protocol will be changed like this ?
