H.264 Encoder Generated bytes too low

Jayakrishnan
Expert 2790 points

Hi All

This question might be too general in nature, but I am looking for an  answer  for the possible reasons.

I have an H.264 Encoder which is integrated into ipnc rdk. The process call  is successful, but the generated bytes are less than expected.

 I have  ensured that static & dyn params are properly set to give a reasonable bitrate. Also set the rcAlgo properly.

  Infact I have copied all the params used in the test  application.

What are the other possibilities ? Pls share from your  experience.

Best Regards

JK

    Dear Jayakrishnan,

    Could you please share all the parameters you are using along with the logs, if any, generated during the process ?

    It would be of great help if you can also share the bitstream, if possible.

    .

    Best Regards,

    Nandu.

    Hi Jayakrishnan,

    In which channel you are facing the issue ? Also how much drop in bit rate are you observing ?

    Best Regards,

    Nandu.

    In both channels. I did not measure the bitrate. For the same set of params , the bytes generated are much more in size in the test app. The decoded frames are blank. Standard decoder  is able to parse the stream properly.

    Also , the bytesgenerated shows an increase in size  when the camera captures some motion. This means, encoder is working. But I don't know why the decoded frames are blank.

    Best Regards

    Hi Jayakrishnan,

    Can you please dump the bitstream from ipnc and send it ? Also we would like to have a look on to the bitstream generated from testapp you were using for the comparison.

    .

    Best Regards,

    Nandu.

    ...


    1. are the parameters the same as your setting before integration ?

    2. download streameye and play your bit-stream with showing info(press info button). Then check if the info is the same as your encode setting like resolution...etc
