Hello :)
I'm using ffprobe to analyze an MPEG-TS broadcast recording that has
problems.
ffprobe finds issues, but I can't seem to find out at what time position
they are :(
For example:
================
[h264 @ 0x148b6e0] Reinit context to 1280x720, pix_fmt: yuv420p
[h264 @ 0x148b6e0] error while decoding MB 0 27, bytestream -13
[h264 @ 0x148b6e0] Cannot use next picture in error concealment
[h264 @ 0x148b6e0] concealing 1489 DC, 1489 AC, 1489 MV errors in P frame
How can I tell ffprobe to tell me the (frame/time-)position of that error?
I'm grateful for any hints :D
Thank you in advance,
Peter B.
Here's the command:
// ------------------------------------------------------------
$ ffprobe -i input.ts -select_streams v:0 -show_frames
// ------------------------------------------------------------
Here's the console output:
(I've "compressed" a repeating error message though)
