Some recordings won't play. Sometimes I get "Decoder Error" message,
some times the frontend crashes. In both cases the frontend outputs a
raft of error messages.
First, it outputs about 50 lines of this:
Decoder decoders/avformatdecoder.cpp:3483:ProcessVideoPacket AFD: video
avcodec_send_packet error: Invalid data found when processing input
(-1094995529) gotpicture:0
Then maybe 70 or 80 lines (I haven't counted them) of this:
CoreContext mythplayer.cpp:3123:PauseDecoder Player(0): Waited 100ms
for decoder to pause
For the decoder error, I tried switching from VAAPI to OpenGL and it
crashed the frontend. I have tried all the playback profile options and
no luck. I think no matter what I pick, it ends up using VAAPI (I know
VDPAU is a wrapper for VAAPI). I also tried disabling the built-in
ffmpeg, which also caused a crash. When I get such a recording, I watch
it with mplayer with no problem (VLC and xine also work).
Another issue I have had is mythcommflag getting hung and having to be
killed. When it doesn't get hung, it only finds about half of the
commercials.
I have been recording most of our shows via firewire connections on two
Comcast cable set top boxes on a master BE/FE and a slave BE. Lately,
however, I have made great strides in improving my antenna system and
have been recording more OTA shows. I have yet to experience any
problems with OTA recordings; no decoder errors, no crashes, no hung
comm flag, and the commercials are detected almost 100% accurately. The
video is MUCH better (file sizes are also MUCH larger).
I have come to the conclusion that Comcast's compression is causing
problems with the recordings. I am concerned that not many users (if
any) are using the firewire STB tuners and that these problems will
never get fixed since the devs (and very few users) ever see them. I am
going to try setting up an external player, but I'd rather see
Mythfrontend get fixed. I'm just not sure how to proceed.
Comments and advice welcome.
