I have some H.265 files that I want to convert to MPEG-4 so I can play them. I installed Handbrake 0.10.5.0, but after selecting the input and clicking Start it completes in about 1 second and doesn't produce the output file. The Activity Log has a lot of stuff, including multiple:
Warning: Could not read data for preview 1, skipped
I can't tell what has gone wrong. Then as a test I tried an MP4 file that I can play and has no problems as far as I know, but the conversion also finished quickly and created no output file. Once it decided the input was a file/stream the log shows:
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'C:\Users\User\Videos\CB(Live on KEXP).mp4':

Again I can't see what's wrong. Any suggestions?

I disabled QuickSync Decoding, but that didn't work. The only other option in Video is DXVA Hardware Accelerated Decoding. It was off but I tried it on and it didn't help either.
Is an experimental version in 'nightly' likely to work if it won't convert what seems to be a routine MP4 file?
I just downloaded an MPEG-1 file from the Hubble Space Telescope website and it failed on that as well.
I know I had this problem with my old graphics card (ATI 4670) and one of the Handbrake 10 versions, causing it to output instantly with a empty file. Filed a bug report on Handbrakes website but it never really went anywhere. Might try Handbrake 0.9.9, but it probably does not have H265 decoding support. Might also try VidCoder.
