FFmpeg retrieve a specific program from TS file

8 mai 2017, par chang jc

I tried to retrieve a specific program from a TS file.
Said :

Then I tried to retrieve a specific program as :

ffmpeg -i INPUT -map 0:p:1344 OUTPUT

It succeeds greatly but the only thing I noticed is :

it seems to apply transcode (decode & encode again) to the output implicitely ?

If so, could I avoid the transcoding by command ? Or it is a necessary ?
It it is a need, WHY ?

Merge commit '1202b712690c14f0efb06e4ad8b06c5b3df6822a'

* commit '1202b712690c14f0efb06e4ad8b06c5b3df6822a' :
theora : export cropping information instead of handling it internally
h264dec : export cropping information instead of handling it internally
h264dec : be more explicit in handling container cropping
hevcdec : export cropping information instead of handling it internally

This commit is a noop.

This changes the cropping behavior, when it's supposedly only meant to move
it outside of the decoder.
See https://ffmpeg.org/pipermail/ffmpeg-devel/2017-May/211239.html for the
discussion about it.
