  • FFmpeg on Azure Function call running slowly and producing an empty output file

    7 novembre 2017, par The Lemon

    I’m trying to make a function which uses ffmpeg, so far I haven’t been able to get anything other than the -version command to work properly. When I try to run a simple ffmpeg -i {input file path} {output file path} command, the function seems to get stuck for 3-4 minutes (in the process creating an empty output file), then try again and produce the error ’file already exists’. I’ve tried switching between the 64 bit ffmpeg.exe and the 32 bit ffmpeg.exe with the function running as both a 32 and 64 bit function. My code and the associated logs from trying to run the code are included below, if anyone can tell me what I’m doing wrong or how to get the process to work it would be greatly appreciated. Thanks in advance, Cuan

    edit : The process works on kudu with the same files, the output is shown at the bottom. On kudu the process ran in under half a minute, clearly something is causing the function process to hang, if anyone has advice it would be greatly appreciated. Thanks again, Cuan.

    second edit : I tried adding the -y to the end of my command, this works in that it no longer complains about overwriting, but alas it now just hangs twice due to timeout. (output at the bottom)

    edit the third : azure has a way to let you run functions locally, my function ran into the same issues on the local version but : as it turns out the actual processing is done within a few seconds, it just takes forever to decide to write to a file - if you terminate the process manually after the process had been running for 10 seconds the file immediately gets written. Again, any help is appreciated. Cuan.

    i really want a way i can be able to map every input stream to have an output stream that can be accessed separately from the other like maybe if i need the first stream maybe i will just

    ffplay http://localhost:8090/feed1.ffm

    and if i need the 7th stream i will just

    ffplay http://localhost:8090/feed7.ffm

    Please can someone help me crack this issue. FFmpeg dont have complex examples for my current situation.

    this is my header information

  • ffmpeg : single input file contains multiple streams, how to save each discreetly ?

    9 octobre 2017, par pinhead

    I have been given a .dvs file which was recovered from some proprietary multi-camera security surveillance system. ffprobe returned errors at first but when I switched the extension to .avc I was able to extract video metadata (output below). ffmpeg was able to read this file and export a long video file that essentially jump-cuts between the different cameras in an erratic pattern, like a crazy music video ! Is it possible to use ffmpeg to identify the different parallel video streams and output each camera source as its own file ?

    ffprobe -probesize 1000000000 output :
