[issue2630] allow copy of timecode from input to output

2011-02-28 Thread Dave Rice 

New submission from Dave Rice daver...@mac.com:

In this case I have a Quicktime file with a video track, audio track, and
timecode track. I want to transcode to a Quicktime file with a different video
codec but copy the audio and timecode to the output. There is no -map_timecode
or -tcodec copy option to actually get the timecode to the output. Dave

[issue2597] have -ffv1 processes be lossless by default where possible (with uyvy422)

2011-02-09 Thread Dave Rice 

New submission from Dave Rice daver...@mac.com:

When using an input that has a -pix_fmt not supported by the ffv1 encoder (in
this case uyvy422), use a comparable -pix_fmt instead of defaulting to yuv420p.
I'd expect (or 'assume') ffv1 will be lossless when possible by default, adding
-pix_fmt yuv422p makes this happen.
Dave


ffmpeg -y -i input.mov -vcodec ffv1 -acodec copy outffv1.mov
