Subject: [mythtv-users] mythtranscode FIFO on master - corrupted mp4 output




Is
 anyone using mythtranscode in FIFO mode on master? I am building a new 
backend on CentOS 7 and while the core systems seem to work well I am 
having trouble with my transcode script which worked on 0.27 / ubuntu 
14.04.

For testing I am essentially using the script from https://www.mythtv.org/wiki/Example_Script_using_mythtranscode_in_fifodir_mode.

Essentially
 the output video is massively corrupted and is a series of horizontal 
lines across the whole screen. Audio appears to have worked fine. 10sec 
example with corrupted output loaded here: https://www.dropbox.com/s/8b1gpuwtza4ndmh/test.mp4


As far as I can see there are no errors generated anywhere in the logging.

<..snip..> Quick update. I tried with a recording from the new system, no change in behaviour. Same corruption is present. I also managed to turn up these:http://lists.mythtv.org/pipermail/mythtv-dev/2015-July/074901.htmlhttps://code.mythtv.org/trac/ticket/12479 Which look very much exactly like the symptoms I am currently seeing. I will endeavour to revert the change and see if that improves things.
