(There may be a "-vprofile baseline" missing after libx264, please test.)
I tested with 2 inputs (SD encoded to h264 and HD encoded to h264). In the both cases, it works with this low resolution.
i transcoded with the following lines:
$ ffmpeg -i test4.avi -s 320x144 -acodec libmp3lame -vcodec libx264 4.mp4
$ ffmpeg -i test5.mkv -s 320x144 -acodec libmp3lame -ac 2 -vcodec libx264 5.mp4
Do you think it's h264 decoder lacks of memory? I see parameter of nvidia module which allow setting memory like NVreg_InitializeSystemMemoryAllocations:int
? Do you have suggestions?
