Help with transcoding h264 encoded TS on raspberry pi

[Stefan Simon]

You're right of course. I took Markus' tar-gzipped sources with configure
"pre-run". make clean, configure, make and all is good. Unfortunately I
stumbled upon a serious problem. When transcoding a stream with aspect
ratio 4:3 is interrupted with a commercial that is 16:9, the pipeline
breaks/stops:

tested with these elements

! progressreport ! tsdemux ! mpegvideoparse ! omxmpeg2videodec ! fakesink

ERROR: from element
/GstPipeline:pipeline0/GstOMXMPEG2VideoDec-omxmpeg2videodec:omxmpeg2videodec-omxmpeg2videodec0:
GStreamer error: negotiation problem.
Additional debug info:
gstvideodecoder.c(2015): gst_video_decoder_chain ():
/GstPipeline:pipeline0/GstOMXMPEG2VideoDec-omxmpeg2videodec:omxmpeg2videodec-omxmpeg2videodec0:
decoder not initialized
Execution ended after 0:03:34.668588841

Is this "works as designed" or a bug?
