Strange transcoding errors
Posted: Wed Apr 06, 2022 6:28 pm
Hi to all!
I have encountered a strange behavior with some video files, and there is more and more of things like this, so I assume this could be something in encoding of the files, but I can not figure out how to solve this inside UMS. This is happening for a while, and I think it is not in relationship with the version of UMS, because it is updated more times when I start to have this and I have tried to go back to earlier versions and have exactly the same problem.
So the main thing is that I use no transcoding when the video is playable on my Panasonic ST50 plasma. And there is no problem.
The problems start if I have to do a transcode because of external subtitles for example, the same video thats working with no transcode I try to play with FFMPEG or MEncoder and now after about 30-40 seconds the audio is muting, the video contiues to play for some time, then I see something like a jump in cutting, and I have audio and video again but not in sync for about 30-40 seconds again, then a jump and so on... Almost the same in FFMP{EG and Mencoder, the differenc may be in how many seconds the synced tile is played and then starts te mutin/unsync problem.
The only transoder that seems to work is VLC, but there are another two problems that I have with VLC, with this one the Video size ratio is always screwed (whatever the source is I have something streched on TV) and the other more irritating thing with VLC is that if I have 10 subtitles inside the container, or have any external subtitles the VLC is showing ALL of them in the same time, and I can not choose witch one to be readable.
In the list before I start to play I can choose witch video I would like to play, to select audio and title combination, but whatever I chosse it will play all the subtitles simultaneously over the screen.
The only workaround that I have found is to cut off all subtitles that are inside the container, to add the one I have externally inside the conteiner with a third party tool, MKVToolnix GUI and to try to play that video with only one subtitle inside the container with NO TRANSCODING, but I can do this only with supported formats from my TV, or to watch these videos with VLC stretched.
But it is pain when I start to watch a mopvie or a series and discover that I have problems with Audi sync and have convert the movie or all the episodes to be playable with NO TRANSCODE...
I would like to be able to play dem with UMS and transcoding, thats more comfortable.
Thanks in advance for your help!
