Other Parts Discussed in Thread: DM3730

I am using dm3730 h264 encoder provided in dvsdk. It works fine at 1280x720, 768x576, 640x480, 352x288, but it segfault on dsp side on the first call to VIDENC1_process with  a 320x240 resolution.

I see a DSP MMU error fault in the log for this resolution.

Any ideas ?

    In opposition to what is written in the encoder user's guide, the width*height*2 is not a good value for the output buffer size. The minimum value returned by XDM_GET_BUFINFO for output buffers may be higher than that. My problem was solved by using a correct value for the output buffer size
