Play still recording FLV file - duration #202

Open modmanx opened 10 years ago

modmanx commented 10 years ago

When I play still recording FLV file, duration and media_end_pos is set at the file load time AVPlayer::load. When video position get's to media_end_pos set at load time, video stops. If I put media_end_pos = std::numeric_limits<qint64>::max(); then video plays as it's suppose, even after position is over duration.

Is it possible to implement a method in AVPlayer where I could manually set the duration and or media_end_pos?

I noticed that MKV file that I'm recording with same options as FLV, gets "Unknown" duration, but it's not seekable as FLV is.

Good question and interesting. I have not considered it. How do you record and play? What about other players?

VLC - When I open the same file (while still recording) it detects the duration but it can play beyond detected duration (fe.: 01:17 / 00:50) As I mentioned, if I set media_end_pos = std::numeric_limits<qint64>::max(); in AVPlayer.cpp@607 (just to test) then your player works fine too.

I'm recording video from Blackmagic device.

the stream must contain information about durations. how can we detect them?
