Missing audio and problems playing FLV video converted from 720p .mov file with FFMPEG
18 novembre 2011, par undefinedI have some .mov video files recorded from a JVC GC-FM1 HD video camera in 720p mode. I have FFMPEG running on a Linux box that I upload files to for encoding into FLV format. The video appears to be encoding ok, but there is no audio in the resulting FLV file. Also, when I play it back in Flash Player, in a browser or on Adobe Media Player, the video pauses at the start. It appears that Adobe Media Player waits for the progress bar to reach the end of the video before starting the playback - i.e. the video will load, the picture pauses, the progress bar seeks to the end as if the video were playing, then when it reaches the end the video picture starts. There is no audio on the video. I am noticing this in the video player I have built with Flash 8 using an FLVPlayback component and attached seekBar. The seek bar will start moving as if the video is playing but the picture remains paused.
Here are some outputs from my FFMPEG log and the command I am using to encode the video.
My FFMPEG command called from PHP :
$cmd = 'ffmpeg -i ' . $sourcelocation.$filename.".".$fileext . ' -ab 96k -b 700k \
-ar 44100 -s ' . $target['width'] . 'x' . $target['height'] . ' -ac 1 \
-acodec libfaac ' . $destlocation.$filename.$ext_trans .' 2>&1';The output from my error log :

19 septembre 2013, par Jingning HanChanged Paths :
Modify /vp9/encoder/vp9_rdopt.c
Remove redundant mv_pred use for sub8x8 blocksThe sub8x8 blocks has its own motion vector reference scheme. The
mv_pred is only used blocks of sizes 8x8 and above, to find the
starting point for motion search.This change does not change any coding behavior. It makes the
encoding process slightly faster. (0.5% speed-up for local test on
speed 1.)Change-Id : I746ee6ef0eac19aa3621be014afa12be8d82cbb9
