"Play Recording From Beginning" - not working correctly

If I'm watching a channel using one tuner and have another tuner in the middle of a scheduled recording then change to the channel that is being recorded selecting "Play Recording From Beginning" I end up at the beginning of the timeshift buffer for the first tuner. This makes it impossible to watch a recording in progress from the beginning.

Currently... the last I knew... this was work in progress.

Excellent, please let me know if there is anything I can do to help! I'm a c# developer but have not had much time to contirbute to MP other than some plugin work.

I'm just checking in that this isn't just my system. My problem is if i am recording a channel (i use mpg rather than ts) and the recording is say half way through i have no way of watching. Neither the play recording from live point nor the play recording from beginning options work for me. I am able to play the recording once it is finished. If i discover i'm the only one with this issue then obviously i've got some digging to do but from what i read above it seems like this is an area which is being worked on.

If anyone can shed some light i'd be grateful

Cheers

This is really a bug.
I am looking into it at the momement

gemx · 2007-03-22, 09:00

It occures only with mpeg recordings not with .ts recordings.
The problem is the tsfile source (async) filter.
Either MediaPlayerClassic nor Windows Media Player are able to play the file while being recorded -> Message: "File is in use".
VLC plays fine.
So no problem with MP itself.
Checking the microsoft knowledge base

Nothing on the microsoft sites BUT
replaying the file via the tsfilesource filter works even during playback

So we just have to change the method where the graph is built to use TSFileSource instead of "File Source (async.)"

Hi gemx,

thats sounds nice. Thanks for your work!

Ok. Found the bug

TSFileSource is already used for mpeg files but the CheckMpgFile() method of the PlayerFactory class raises an exception because it can't access the file. So it returns "false" which means that it is not a valid mpeg file.
So the playerfactory creates a Videoplayer which uses the microsoft file source which can't replay the file.

Alright, fixed it

It should be working in the actual snapshot rev. 13518

Please provide some feedback if it's really working as desired.
Thanks.
