64 bit ffmpeg update - some fixes and bugs

[vidrep]

Updated 64 bit to hrev49881 Played a variety of SD and HD format videos with MediaPlayer Played a variety of YouTube videos on Webpositive AVCHD (mt2) video is now working again with MediaPlayer 4K UHD (MP4) video is now displaying video with MediaPlayer (Heavily CPU dependent) SD (avi) not working with MediaPlayer - MediaPlayer closes immediately YouTube video plays in Webpositive, BUT at double speed

I'll attach logs after further testing tomorrow

Is WebPositive working as in x86_gcc2? I think MediaPlayer isn't comparable, as it uses the older ffmpeg.

Web+ works at double speed on youtube also on x86_gcc2. The code there relies on the timestamp for audio and video frames to be correct, and apparently one of them isn't. This is tracked in #12460.

As usual, for MediaPlayer problems, a sample file is welcome, maybe from the ffmpeg/mplayer shared sample collection: ​https://samples.ffmpeg.org/ / ​http://samples.mplayerhq.hu/

If you want I can split this ticket up to address each issue individually. The Web+ issue is already known and tracked in #12460. We also have open tickets for the other issues, albeit they are not 64 bit specific. What do you guys suggest?

[pulkomandy]

I think the best way is, have a look at the generated debug reports for crashes, you can see if the error message and backtrace look similar or very different, and try to report a single ticket for a single issue.

We can always split or merge tickets later on, in case it turns out the initial sorting wasn't correct.

I was just looking at another related ticket #12491 (also mine), and noted that 32 bit Haiku behaves exactly the opposite of 64 bit in MediaPlayer when playing the same videos. AVCHD - 32 bit crashes, 64 bit plays perfectly 4K UHD - 32 bit crashes, 64 bit plays perfectly (only with Core i7 minimum) SD 640x480 - 32 bit plays perfectly, 64 bit crashes

What's the connection (if any) here?

I attached the results of my tests to ticket #12491.

Please close this ticket as it has been superseded by ticket #12508.
