#3315: Rewinding/fast forwarding above 3X doesn't work with libmpeg2, but does
with Standard/ffmpeg

 Reporter:  anonymous  |       Owner:  ijr       
     Type:  defect     |      Status:  new       
 Priority:  minor      |   Milestone:  unknown   
Component:  mythtv     |     Version:  0.20-fixes
 Severity:  medium     |  
-----------------------+----------------------------------------------------
 I use ATrpms 0.20-fixes r13228 (and ATrpms libmpeg2_0-0.4.1-3 and ATrpms
 ffmpeg 0.4.9-19_r7407, all on Fedora Core 6 64-bit on EM64T), but this is
 a problem I've had since my first days of MythTV more than a year ago.

 Rewinding or fast forwarding recordings--whether HD or not--during
 playback has never worked right for me. 3X works fine as far as I can
 tell, but any faster speed (5X, 10X, etc.) means that the video will stop
 "moving" after four or five seconds. Pushing Play always resumes playback
 normally, so it's not quite a duplicate of #745 or #2434 (which involve
 different hardware, anyway).

 I never bothered to report the issue because time skips are a very
 adequate substitute. However, very recently I've discovered that this is
 only an issue with the libmpeg2 decoder; using the Standard/ffmpeg decoder
 does permit rewinds and fast forwards to work properly. (I don't know
 whether in the past this issue existed with both decoders, but that's the
 way things stand right now.)
