Enabling snapshot will enable MJPEG channel to output an encoded frame. The actual bitstream will be received via the usual

Venc_getBitstreamBuffer() API where the channel number in the bitstream indicates the encoder channel.

Hi Badri,

How can I confirm the contents of BitstreamBuffer belonging MJPEG channel?strmId?

You can use chnId. For netra progressive usecase MJPEG encoder channel numbers are 32 - 47.The chnId will match the vencChnId passed in Venc_snapshotDump() API.

Hi Badri,

As you said, I checked the channel number and the vcodectype was 2.

Thank you!
