DM8107 dropping frames at 1080p60 encoding

Sebastian Ceola
Prodigy 130 points

Hello.

I'd like to request some help with the following issue, I've been reading posts left and right about very similar problems but still haven't been able to fix it.

I'm trying to encode a 1080p60 stream, however, the encoder seems to be dropping frames.  This is my usecase:

        vip --> dup --> merge --> dei --> nsf --> enc

Looking at the statistics logs (attached at the end) the nsf link seems to be dropping frames.  I assume this is because, further down the chain, the encoder appears to be stuck at 50fps and causes the nsf buffers to fill up... that is, if I'm reading the logs correctly.

This are the clock settings:

ARM clk: 720MHz
DDR clk: 533MHz
L3 clk: 200MHz
IVA clk: 440MHz
ISS clk: 500MHz
DSS clk: 200MHz
DSP clk: 750MHz

I'd appreciate it if someone could help me sort this out.

Thank you.

    Hello,

    Could you check allowFrameSkip is not set?
    0 - Frame can never be skipped

    Hello,

    I'm using the DVR-RDK version 4.0.

    FrameSkip is not allowed.  About this though, even if it were allowed, would it matter?  I'm giving it plenty of bitrate so I don't see a reason why it should be skipping frames.

    Thanks.

    I decided to reduce the usecase to remove as many variables as possible.  This is the new one:

    vip --> enc

    It's still dropping frames reaching only 50 fps.  The new statistics log is attached at the end.

    There are some messages about batch processes breaking due to exceeding a size limit, what do these refer to?  Are they relevant in some way?

    Hi,

    Capture is still capturing at 60fps , but it is dropping lot of frames, dropped frames = 735. Which means, capture is not receiving frames in time, some link in the chain is running slow. Because of this capture is dropping frames. Hoping that you have not enabled skip frames in the capture driver.

    Rgds,

    Hello,

    As far as I can tell, the only way to configure the capture link to drop frames is with the CAPTURE_LINK_CMD_SET_FRAMERATE_DIV command, is that correct?  In that case, no, I have not configured it to skip frames.  I know you can also set the encoder to allow frame skipping, this is disabled too.

    I'm using a high target bitrate as well to remove any sort of bottleneck there.

    If you look at my first post, with the more complex usecase, most of the frames seem to be dropping at the NSF link, which is right before the ENC link.

    Is there any way to verify which link is running slow?  Given all of the above and that the IVA-FPS is stuck at 50 makes me think the problem might be at the encoder, but I'm not entirely sure.


    Thank you for your help.

    Best regards,

    Sebastian.

    Hi Sebastian,

    NSF can drop the frames if it is running out of output frames. If the encodes is not returning frames in time to the Nsf link, Nsf will run out of frames and start dropping/returning frames back to the previous link. Can you increase the number of frames in nsf and see if if improves the fps?

    Also add some time stamping in the encoder link and see if it is able to complete frame processing in real time. 

    Regards,

    Brijesh

    Hello,

    I tried doubling the number of output buffers after the NSF link in the first usecase and after the VIP link in the second usecase.  Is this what you meant?  If that's the case, frames are still being dropped.

    Do you mean the timeStamp field in the output buffer you get from the ENC link?  That one is enabled already.

    I've been trying some different parameters and it seems that this issue is only present when enabling the use of B-frames in the encoder.  If I use only I- and P-frames then the encoder is able to reach 60 fps without a problem.  I've tried changing other settings such as GoP length and HRD buffer size, they seems to affect the output frame rate a tiny bit but not enough to reach 60 fps.

    Could it be that there isn't enough bandwidth to encode 1080p60 with B-frames?

    Regards,
    Sebastian.

    Hello Sebastian,

    Could you share the encoder's params that are set when the B-frames encoding is enable?

    What is the bitrate that you are setting in case b-frames and 1080p60?

    Hello Margarita,

    The encoder settings are attached at the end.

    I've tried with different targetBitrate settings, from 6 Mbps all the way to 20 Mbps.  I don't think it mattered though because the encoder is only using around 1~3 Mbps for this particular stream.  The current test video stream is the standard SMPTE color bars at 1080p60 obtained from a signal generator.

    Regards,
    Sebastian.

    Hi Sebastian, 

                By enabling B frame, the DDR Usage & Bandwidth will increase. H.264 Encoder is capable of doing 60fps Encoding for the given parameters.

    Can you make sure that you had provided enough buffer of memory to each chain because in case of B frames memory requirement increases & Encoder hold more frame than the P frames case. So allocation wise if less buffers are allocated to Codec or any other modules then frame drop observed.

    Regards

    Hello,

    In the basic usecase of just VIP --> ENC I've assigned the maximum number of buffers to each, that is:

    ENC_LINK_MAX_OUT_FRAMES_PER_CH to the ENC link (numBufPerCh[0]).
    CAPTURE_LINK_MAX_FRAMES_PER_CH to the capture link (numBufsPerCh).

    I'm only using one channel in each link.  Is there any other buffer I should be configuring that I'm not aware of?

    Regards,
    Sebastian.

    Hi Sebastian,

    I don't have complete idea of DVR-RDK & its memory usage. And also I hope you have enabled TILER memory which will impact the performance as well. Check also the DDR Usage in case of B frames.

    Regards
