ebr 14960 Posted October 31, 2016 Share Posted October 31, 2016 I'm afraid you've exhausted my AV knowledge. What does 1 ref frame mean? Where can I check this? The video I sent you plays in desktop and iOS emby apps, and it used to play fine on the Fire stick before the recent update. It never needed transcoding, and I'm pretty sure it direct-played, though maybe it direct-streamed. So if there's anything "non-standard" about this video, it seems like past version of emby for Fire Stick was robust enough to handle it, while the new version isn't. Or am I mistaken? Pretty sure the previous version was transcoding it. Link to comment Share on other sites More sharing options...
elenev 0 Posted October 31, 2016 Author Share Posted October 31, 2016 Ref frames: I didn't do a completely rigorous test that would perfectly isolate the problem to the 1 ref frame. However, it's very likely. Other episodes of this series also have 1 ref frame and also won't play. Episodes of another series encoded roughly the same way (also H264/avc1 for video, 2-channel AAC for audio, mp4 container, differences are audio bitrate (44K vs 48K), video level (21 vs 31), video framerate (24 vs. 23.98...), resolution and aspect ratios) but with 5 ref frames instead of 1 play fine. A video with 9 ref frames (now that I read up on this, this seems like too many) also plays fine.Transcoding: Don't mean to argue, but I'm pretty sure it wasn't transcoding before. The reason for my confidence is that I used to have problems playing this series (all encoded the same way) about three months ago. I spent a lot of time trying to figure out what was going on (it ended up being the bitstreaming settings on the emby Fire TV app). But in the course of trying to figure it out, I looked at logs and tracked any changes to the transcoding-tmp folder. There were no calls to ffmpeg and no temporary files created. For other videos (e.g. some old ones I have that are Xvid in avi containers), evidence of transcoding was clear. Link to comment Share on other sites More sharing options...
ebr 14960 Posted October 31, 2016 Share Posted October 31, 2016 Did you find any items with only 1 ref frame that did play properly? Link to comment Share on other sites More sharing options...
elenev 0 Posted October 31, 2016 Author Share Posted October 31, 2016 I haven't, but I haven't tested that many, and they were all episodes of the same series, encoded identically. Is there to search for all 1 ref frame videos? Perhaps a way to export the database, including codec info, to a CSV? Link to comment Share on other sites More sharing options...
CBers 6804 Posted October 31, 2016 Share Posted October 31, 2016 Not sure if this is related, but I thought I'd ask rather than starting a new thread. I have 2 MP4 videos with Ref Frames = 1, which play audio, but not video.

elenev 0 Posted October 31, 2016 Author Share Posted October 31, 2016 Works in 0.70 beta! It's being transcoded, so it took like 5-7 sec to start playing, but that's ok. Video quality of the transcoded stream doesn't seem worse than before (or than direct-playing on my PC) and it doesn't stutter, at least not in the first 20 seconds which I just watched.Here's an excerpt from the transcode log. Input and output seem almost the same, so I'm still not sure why it needs to transcode...

ebr 14960 Posted October 31, 2016 Share Posted October 31, 2016 It is just doing a container swap which appears to correct whatever the issue is with a single ref frame. Link to comment Share on other sites More sharing options...

elenev 0 Posted October 31, 2016 Author Share Posted October 31, 2016 Not seeing .70 here at the moment, on either of my Shield TV's. Will check again later. Didn't work for me at first either. On my Fire stick, I deleted it from the device and then used "Send to device" from Amazon's web interface. Perhaps my experience is somehow applicable even though your device is different.
