I’ve got a transcoding problem with a particular brand of MPEG-4 encoders. In particular, I have several Optelecom (i.e. Siqura) C50e MPEG-4 encoders and whenever I try to transcode the incoming video to H.264 I see the following error in the logs:
TranscoderWorkerVideoDecoder.frameDimensionsValid[_defaultVHost_:atmslive/_definst_/Opt-C50e-MPEG4-unicast-98.207.stream: decodeIterations:0]: videoDecoderDecodeDisplayWidth failed [0:32:8192]: Encodes will not be playable
The end result is that the transcoded video never becomes available. I’ve got other other MPEG-4 sources that transcode with no issues using the same Wowza instance. I didn’t find anything similar in the forums or doing a Google search. Is this an issue with the encoder itself? VLC has no problems playing the MPEG-4 video stream from the encoder. Any suggestions?
