[FFmpeg-devel] [PATCH v2] lavf/matroskadec: Set A_QUICKTIME bit depth

Since mkvmerge doesn't set the bit depth for A_QUICKTIME audio (as far as I know), the track->audio.bitdepth variable will be zero, and its value needs to be retrieved from the sound sample description. Also, confine the 0x to 'raw '/'twos' fourcc mapping to old version 0 sound sample

[FFmpeg-devel] [PATCH] libkvazaar: Set frame rate as a rational number

[FFmpeg-devel] [PATCH 1/2] ffplay: Seek only when pressing the right mouse button on the video window.

Seeking by clicking on the video window can be annoying, because the user might click on it accidentally while eg. trying to get focus on it, and ffplay seeks instead. This commit changes that behaviour to seek only when the right mouse button is used to click and drag on the window.
