Hello. I have an issue with using yadif and OpenCL (opencl with the latest

about them.

Using the option '-ac 2', ffmpeg 0.6.7 works.
But, using the same option, the current version from the master git branch
doesn't work.

Thanks! With this, 0.6.7 runs but newer versions still complain about:
[alsa @ 0x55eb8e2a6780] cannot set ALSA buffer size (Invalid argument)
hw:1,0: Input/output error
Any idea?

Hi,
I am trying to run FFmpeg 3.3.3 windows static binary on windows docker
container, same binary which works perfectly on normal windows machine.
Incase of docker, looks like the process itself is not getting launched
when ffmpeg.exe command is run. I don't see any error either. Strange

Thanks Gyan
That improved things slightly. The difference is pretty noticeable though to
the output I can get with Premiere.
Do you know if you can specify the colour bit depth for the png file?
