These are the actual recorded MPEG data files. In order to keep the size of
|
||||
an individual file below a given limit, a recording is split into several
|
||||
files. The contents of these files is "Packetized Elementary Stream" (PES)
|
||||
and contains ES packets with ids 0xE0 for video, 0xC0 for audio 1 and 0xC1
|
||||
for audio 2 (if available).

- Increased timeout until reporting "broken video data stream" when recording.
|
||||
- Modified method of turning off PIDs when switching channel.
|
||||
- Increased amount of non-useful data received by cRemux before assuming the
|
||||
recording will fail.
|
||||
- If there are two audio PIDs defined for a channel, both audio tracks will
|
||||
now be recorded and can be selectively replayed later. See the FORMATS file
|
||||
for details on how these different audio tracks are stored in the recorded
|
||||
files. In order for this to work properly you need to make sure that the
|
||||
StartHWFilter() function in the driver's 'dvb.c' has
|
||||
|
||||
u16 mode=0x0320;
|
||||
|
||||
instead of the default
|
||||
|
||||
u16 mode=0x0820;
|
||||
|
||||
This will create packets for the second audio track that are small enough
|
||||
to multiplex smoothly with the video data.

to toggle between these. There can be two different audio PIDs per channel,

assuming that typically a channel broadcasts a country specific language

plus the movie's original soundtrack.
|

Recordings made form such channels will contain both audio tracks, and when

replaying the desired audio track can be selected the same way.
