Replying to cehoyos:
Please test current FFmpeg git head and please provide the input sample.
Double checked that I had git head installed and ran again. Same error. This error happens with any mp4 but I have now provided a sample mp4 that can be used.
This error occurs when using 00:00:03
, 3
or 3s
as a seek argument. 3 is simply there as an example. Any amount of time will not provide proper output.
