mpegpsdemux: Unable to play backward
How to reproduce:
gst-play-1.0 medias/defaults/mpegps/sample_mpeg_program_stream_scr.mpg
and then press the key "d" to play reverse
Results:
Reverse playback is not working where no frame will be decoded.
Analysis:
After some investigations, no i-frame is sent by mpegpsdemux/mpegvideoparser, so the decoder does not decode anything. It receives only b-frame. This media is using a non zero SCR.
