Well it's a bit of a hack on top of a script I used to test h264 and as I use ffmpeg git via bash alias (ffm) I further modified a bit so it should work for you, assuming you have a working ffmpeg. IME ffmpeg may silently fall back to s/w, so you need to check cpu usage. The threads 1 may not be needed. Normally with x264 md5sum matches s/w decode (with caveats which is why there are different workarounds in parts of the script that won't run as it is). vc1 it seems mostly doesn't sum the same as s/w dec so the script just compares to the first run. I use LFS and have 8 gig ram I made /mnt/ramdisk and then do - mount -t tmpfs -o size=6200m tmpfs /mnt/ramdisk of course tmpfs can get swapped out and you'll need to size for your mem/needs and adjust the paths/filename in the script as required. > > Testing with a h264 video, it worked perfectly every time. > > The "asf_with_chapters.wmv" video works fine for me with software, but shows > garbage with hardware. OK, so my ffmpeg has regressed, another bisect to do :-)</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
