Sam Hocevar	3115550abe	doc/examples/muxing: Fix av_frame_make_writable usage This patch moves the av_frame_make_writable() call from fill_yuv_image to get_video_frame so that its argument can be the actual frame that will be sent to the encoder. This fixes data corruption issues in codecs that keep references on one or several previous frames.

Stefano Sabatini	e34ad128a3	examples/muxing: reduce duration, remove wrong and misleading comment Set duration to 10 seconds, after it was increased from 5 to 200 seconds in `8d80f3cb87`. 200 seconds will generate too much data which is annoying especially when testing.	11 years ago

Andre Anjos	23ffc4c70d	doc/examples/muxing: Fixes frame initialization. Fixes use of the example with encoders which use tha AVFrame w/h/pix_fmt fields FFV1 is one of these codecs We cannot easily workaround the not set fields in common code because the API has AVFrame constant for the encoders. Alternatives would be to fix the API or to duplicate the struct and fill in missing fields. Or as is to require all user apps to set this correctly and maybe simplify for that case Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

Stefano Sabatini	80bca6eabe	examples/muxing: honour distinction between encoder PTS timebase and stream timebase Fix PTS set on the frame when encoding, which must be specified in the encoder timebase or this will confuse the encoder. When muxing the packet, the PTS/DTS generated by the encoder is then rescaled to the stream timebase.	11 years ago

Nicolas George	9b211c43dc	examples/muxing: fix memory leak. Do not re-call avcodec_get_context_defaults3(), it is already called by avformat_new_stream() and it leaks the codec priv_data that was already allocated.
