I continue to have problem with getting ffmpeg to correctly process the video
file that VLC has no problem playing.
sample file: https://0x0.st/iFWC.m2ts
As per suggestion, I tried upgrading ffmpeg to 4.3 and probesize and
analyzeduration:
ffmpeg -i aa.m2ts -analyzeduration 2147M -probesize

The video file can be processed by ffmpeg, but it loses pts, skips multiple

Also, try a newer version- "ffmpeg

I did a transcode from H.264 to H.265 via Handbrake, then tried ffmpeg. Results:

Don't know about PI2, but in general, use ' -vcodec h264_omx' for PI's hardware
acceleration.

Hi folks,
Can anyone help me understand how to trigger ffmpeg to list the resolutions and

With dshow on windows the options can be listed, with avfoundation on macOS you
can pass a bogus frame rate and it lists the valid ones

Certainly is (why did you use it in the first place?). I think you need to

I told that it is a mistake to use sudo when configure and make, so I started

Hello all,
I have never compiled FFmpeg and have zero knowledge nor experience with the
