AW: gst-omx decoding H264 from Logitech C920 stream

[Thornton, Keith]

Do you know if the recordings are in avc or byte-stream format. What does your pipeline look like? Is there a h264parser in the pipeline? Have you tried using it to convert between avc / byte-stream?

Betreff: gst-omx decoding H264 from Logitech C920 stream

Hi,
I have been using the omx264dec to decode a stream coming from a camera, the Logitech C920 which provides an h264 stream, in a Raspberry PI.
When I try to decode this stream with omx264dec the video is mostly corrupted getting a bit better if there is motion in the video.
According to my tests the omx264dec works correctly with Apple's h264 sample file and it also works well decoding video encoded by omxh264enc but not video encoded by x264enc.
On the other hand I have tried decoding the stream of C920 with avdec_h264 and the output is not corrupted at all, leading me to believe in a omx decode bug or incompatibility.
This problems are reproducible with gstreamer version of raspbian.
Can anybody suggest a solution or should I file a bug?
Thank you
Paulo Neves
