comment:1 follow-up: Changed 5 years ago by bf4648

when I play another video in VLC from the same security camera, I'm getting the following error:

VLC does not support the audio or video format "Q264"

I can't decode that video as well using ffmpeg, does ffmpeg need to be updated to support that codec?

comment:2 Changed 5 years ago by bf4648

when I play the video in VLC it gives me the following details on the Codec:

Stream 0

Type: Video
Codec: Motion JPEG Video (QIVG)
Resolution: 352x288
Frame Rate: 30

I'd would like to use ffmpeg to decode the video into mp4 and also use a new audio and video codec if that is possible.

  • Resolution set to worksforme
  • Status changed from new to closed

I cannot imagine why it does not work for you, after making sure we are testing the same sample I suggest you:
Clone FFmpeg into a new directory, run './configure && make' without any additional options and try again.
If it still does not work, please reopen this ticket, but I currently don't know what else to try.
(Remuxing also works fine.)

Replying to bf4648:

I can't decode that video as well using ffmpeg, does ffmpeg need to be updated to support that codec?

Command line and complete, uncut console output missing (in ticket #557), this also works fine for me with the version you tested here.

Sorry that one does work fine but I have others that aren't working. I'll just create a new ticket though.
Thanks,
