Hi,
I use softdevice in my VDR with DirectFB.
Since some time I have the following problem when I replay an
recording. When I fast forward the recording, it runs forward
extremely fast for the first minute (of recording time) or so. Then it
goes to normal ff-speed. The same if I rewind. Also jumping forward or
backward by 1 minute (green and yellow button) is not a minute.
Forward it jumps more than 1 minute. Backwards it is less then 1 minute.
I found out that this change came on 15. April 2008. After some more
investigating I found, it hat to do with the change from
av_read_packet to av_read_frame.
The following patch changes back from av_read_frame to av_read_packet
and so fixes the problem.
Could someone confirm this?
And why did we change from av_read_packet to av_read_frame?
