keith2045 7 Posted January 30, 2020 Posted January 30, 2020 I'm having problems playing specific movies i got recently. I've tried on both the FireTV app and just using Chrome but at specific points in the playback the image becomes distorted, or freezes on the image but the audio keeps playing. This seems to happen at the same spot in video playback. One specific time that it always happens is around 7:07 This issue seems to happen in all 3 of these movies thanks in advance ffmpeg.txt embyserver.txt
ebr 16184 Posted January 30, 2020 Posted January 30, 2020 Hi. Have you tested the video with an independent player?
keith2045 7 Posted January 30, 2020 Author Posted January 30, 2020 Yeah, playback in VLC works just fine. No issue at the specific point discussed above.
Luke 42079 Posted January 30, 2020 Posted January 30, 2020 It could still be a problem with the source file and Vlc just being more resilient at not tripping over it. Can you supply a log example from fire tv playback? Thanks.
keith2045 7 Posted January 31, 2020 Author Posted January 31, 2020 Attached Just more details, every so often the video pauses for a second but the audio keeps playing. It appears to be the same location every playback. I can try to work on the video source, might take me a bit Thanks ffmpeg.txt embyserver.txt
keith2045 7 Posted January 31, 2020 Author Posted January 31, 2020 Nope, same problem. I've attached an updated log file if that helps ffmpeg.txt
Happy2Play 9780 Posted January 31, 2020 Posted January 31, 2020 Does it play without issue if you played the secondary audio track?
keith2045 7 Posted January 31, 2020 Author Posted January 31, 2020 Interesting, yes. The video has 3 audio tracks, the last 2 are commentary tracks. With the 2 commentary tracks it plays fine, but does not play correctly with the main audio track.
keith2045 7 Posted February 4, 2020 Author Posted February 4, 2020 I've only noticed it on 2 movies, this one and MIB 2
Luke 42079 Posted February 9, 2020 Posted February 9, 2020 Have you considered converting those two files using our media conversion feature?
keith2045 7 Posted February 10, 2020 Author Posted February 10, 2020 (edited) I figured it out. I was using MKVToolNix to change the names of the audio tracks. *EDIT* actually not sure what it is, but happens after i edit it using MKVToolNix for the audio titles. Will dig further later Edited February 10, 2020 by keith2045

Let us know if you find anything. @@softworkz is there an easy way to compare the mkv's before and after to see what might be wrong with the edited one?

Please let me know in case you'd need any help with that.

softworkz 5067 Posted February 11, 2020 Posted February 11, 2020 Please activate all options of "EDD File Generation". Then watch the one video for 30s. After that, watch the other video for 30s Finally you should see two files in the log folder having an extension of '.edd'. Please send me those via PM, Thanks!

Will dig further later I think what you did is much more than changing track titles (maybe unintentionally though). Here's a detailed comparison of the metadata: mkv_compare.pdf But I don't think that it's the metadata. What I've seen is a significant difference in the frames of the TRUEHD stream: Look at timestamps and PacketPos values. (all other streams are very similar when looking at the single frames) Whatever you did to the file - something wrong happened.
keith2045 7 Posted February 17, 2020 Author Posted February 17, 2020 Well that's a bummer. I've done the same thing for a dozen or so other files and havent noticed anything. Guess i cant do it for these ones Thanks for the help
softworkz 5067 Posted February 17, 2020 Posted February 17, 2020 Hm, I don't know what happened, but we cannot provide support for 3rd party tools and how to use them (better don't at all) - I've already spent too much time on this. Maybe @@Happy2Play can provide some more hints as he had the right idea pretty quickly. (not to use the TrueHD stream)
keith2045 7 Posted February 17, 2020 Author Posted February 17, 2020 No i get it, dont blame you. I think i've fixed it. I reran MKVToolNix on a Linux machine using the CLI rather than on my windows machine. Initial testing appears to be good. Again i appreciate the help with this 1
