• input.mod : could not find codec parameters [closed]

  8 février 2021, par JustBaibe

  I am trying to covert a .MOD file to .MP4 or .M4V using FFmpeg but getting an error. I have tried adding codec from X-Lite because thought might be missing something that allows reading .MOD files but still getting the error.

  


  This is the ffmpeg command I used :

  


  ffmpeg -f mpeg -i "input.mod" -vcodec copy -acodec mp2 -ab 192k "output.mp4"


  


  and this is what I received :

  


  ffmpeg -f mpeg -i "input.mod" -vcodec copy -acodec mp2 -ab 192k "output.mp4"

input.mod: could not find codec parameters


  


  I've tried just pulling up the file using ffprobe and got :

  


  "input.mod: could not find codec parameters". 


  


  When I've tried to open the file using X-Lite (MPC-HC 64), it says "Not rendered".

  


  Trying to at least play the file. Do I need to covert it to something else instead, like Webm ?

  


  Readout for just ffmpeg -i input.mod

• Ffmpeg inaccurate cut duration with ts [duplicate]

  30 juillet 2020, par Lemon Sky

  I need to accurately seek and cut a video. Some online sources say put -ss in front or after the source. The result is the same for me. In the examples below, the start time is accurate but the duration is not accurate.

  


  ffmpeg -y -ss 00:00:05 -t 00:00:05 -i http://tyberis.com/output.ts 5s.wav
ffprobe 5s.wav

Duration: 00:00:04.74

ffmpeg -y -i http://tyberis.com/output.ts -ss 00:00:05 -t 00:00:05 5s.wav
ffprobe 5s.wav

Duration: 00:00:04.74


  


  Sometimes the starting point is not accurate but the duration is. This is clearly audible by cutting the ts file and cutting an uncompressed wav file, and listening to both.

  


  ffmpeg -y -i http://tyberis.com/output.ts -ss 00:00:15 -t 00:00:05 5s.wav

ffmpeg -y -i http://tyberis.com/output.wav -ss 00:00:15 -t 00:00:05 5s-reference.wav


  


  What fixes the starting time is if I use an m3u8 file that contains the byte offset for every keyframe AND I put the -ss option in front of the source file (if I put it after the source, the start time is inaccurate but the duration is accurate) :

  


  ffmpeg -y -ss 00:00:15 -t 00:00:05 -i http://tyberis.com/output.m3u8 5s.wav


  


  This fixes the start time but the duration is at the location that I would get had I used no m3u8 file (duration is just 4.47s).

  


  It seems different timestamps are involved, and sometimes one or the other gets used.

  


  The ts file was generated by capturing a UDP stream and storing it with ffmpeg and -codec:v copy.

  


  Is ffmpeg broken, or the ts file ? How do I work around this issue or fix the ts file ? What I realize is that the video starts later than the audio, probably because the video does not start with a keyframe. Can I get ffmpeg to start the -codec:v copy after the first keyframe ? What I also notice is that using ffprobe reports "start : 1.400000". Can I force it to start at 0 ?

  


  Any hints would be appreciated.

  


  I tried both ffmpeg 4.3.1 and ffmpeg git-2020-07-24-21442a8.

  


• ffplay -noborder option missing argument

  10 janvier 2021, par Tomás Arturo Herrera Castro

  If I do :

  


  ffplay -i vid.mp4


  


  ffplay works fine, however if I try the borderless option :

  


  ffplay -noborder -i vid.mp4

Failed to set value '-i' for option 'noborder': Option not found


  


  Trying the -noborder option at the end of the command :

  


  ffplay -i vid.mp4 -noborder

Missing argument for option 'noborder'


  


  Any clue on the argument -noborder is waiting for or why isn't this working ?

  


  This is the ffplay version I am using :
