749ddc14fc ffprobe: add priv_class field to Writer, and factorize writer options initialization 2012-09-11 22:30:23 +02:00

cdea19e75a ffplay: increase sample array buffer 
A decoded and resampled audio frame may not fit in the current size which is
not handled by the current code causing out of order waveform displays or even
channel mixups. A todo is added because this part can certainly be improved to
consume less memory but work reliably for any frame size.

81f26d6990 ffplay: ensure that pictq_prev_picture never fills the picture queue 
It was theoretically possible for pictq_prev_picture to fill the picture queue
which may have caused problems when a write to the queue was still in progress.

99b01e458c ffplay: simplify picture allocation 
This also makes sure the aspect ratio of the picture is set before allocating
the picture, this way video_open can calculate with the correct aspect ratio
even for the first frame.

1d0048cfe3 examples/muxing: rename img_convert_ctx to sws_ctx

bdd9bfbbab examples/muxing: prefer AVPicture to AVFrame, when feasible 
Favor the use of plain AVPicture over AVFrame, especially when the use of
AVFrame is not required like in the case of tmp_picture.

Also adopt more straightforward names, to avoid frame/picture confusion.
