as with lengthy events broadcast on the bbc such as sport relief, london marathon, children in need etc. sometimes i only wish to record the parts i want like a sketch or performance rather than the whole programme.

is there a command that let's you record from your own start and end times?

thanks

There are two options used to start/stop recording at prescribed time offsets. See if you can spot them:

Yes, I did spot it but it doesn't work for me. What am I doing wrong? I tested around 4 minutes on The Micheal McIntyre Show from Monday night.

Code:
C:\Program Files (x86)\get_iplayer>get_iplayer --pid=b041c55d --start=00:01:15 -
-stop=00:05:12

Actually, it probably did work. You should have been left with a playable .partial.flv file. You get the "Download may be incomplete" message because it is - you truncated it by design. Using
Code:
--start
and
Code:
--stop
isn't pretty, but it does work. You just don't get nicely tagged MP4 files.

Some further tips:

If you use
Code:
--start
, also add
Code:
--raw
to prevent get_iplayer from launching ffmpeg to re-mux the .partial.flv file. If the recording doesn't start at the beginning of the stream ffmpeg chokes, so all you can get is the .partial.flv file.

Use
Code:
--attempts=1
to prevent a lot of spurious retries. get_iplayer can't tell if the recording is incomplete due to another error or due to use of
Code:
--stop
, so it will kick off retries that are useless in this case.

You can cut down the number of retries a bit further by narrowing the list of recording modes attempted, e.g.,
Code:
--modes=flashhd
to limit attempts to just HD streams.

Thank heavens for that, I'm glad it worked. Thanks for the help and tips user-2.
