testing MrMC 3.0.4

[davilla]

I tried several hevc media; still stuttering; lip-sync issues without transcoding. With transcoding, smooth video but frequent lip-sync problems. So, still the only way to play hevc correctly on ATV4 is Plex.

mediainfo on those problematic hevc's would be helpful.

I use VLC to get the media info; is there another way from MrMC directly?

Re HEVC on the ATV4...

The HEVC files I have stutter still. It could be because they are all 10bit. Unfortunately for testing purposes I recently got rid of 2 HEVC encodes that were not 10 bit.

So, I downloaded some test files from jellyfish, 3mbit/s main and main10. Unfortunately, I couldn't get them to play. I think because there's no audio track they just sit on the first frame or something.

edit: version of MrMC on Shield plays the jellyfish files just fine, with AMC or ff-hevc. Downloaded the h264 3mbit/s file and it also does NOT play on the ATV4, even with VTB. So, it's the new ffmpeg demuxer or something that gets hung up with no audio in the mkv.

1) Guardians.of.the.Galaxy.2014.HDR.1080p.IMAX.HEVC.10bit.DTS-HD.MA.7.1; 22.4Mbps; 23.976 FPS (this is a tough one!)
2) Batman Returns 1992 1080p BluRay x265 HEVC 10bit AAC 5.1; 994Kbps; 23.976 FPS (easier; playable but with clear stutter)

EDIT: pls check ABC Player for ATV4 for comparison purposes.

To be honest, I gave up on HEVC 10bit playback on ATV for now, with any player! MrMC 3.0.4 has definitely improved over previous versions in this regard and other players are struggling too, with more or less success, but the playback is just not smooth enough above 720p (or sometimes even 1080p at a low rate).
Either Apple makes the API for HW acceleration publicly accessible (I wonder why not?) or the next ATV generation with A9 or A10 will solve the problem.

It was the default 20MB buffer size, and buffer all internet

Changed to all files and 200MB, and strangely there seemed to be an even longer startup for playing (but frozen seeing all the files in the directory and the video thumbnail) and the playback was definitley less smooth

Updated to 170503.1539, and enabled debug logging
Same behaviour with 200mb and áll files'caching - long startup and GoPro video stuttering

Changed back to 20mb and internet files caching - Video startup still took a while but this time the first video frame was immediately fullscreen (frozen), and playback was again choppy after about 15 seconds of play time

The longer sample I've been using can be grabbed here;
https://dl.dropboxusercontent.com/u/472 ... r_test.MP4 (356mb)

And third time is the charm Finally tracked down the real issue. A three line fix. I've reverted the previous 'fixes', they were causing issues with other areas. All three samples (including the longer sample) now play perfectly, without any startup delays.

Nice - look forward to testing

I figured your silence on what I wrote above meant you were busy coding to fix. Thanks!

new version pushed up to the usual suspects.
