  • How can I convert a bitmap array to a jpg [on hold]

    31 mai 2014, par user3678446

    There is really not a lot of information about ffmpeg out there. And I thought maybe somebody can help me with this.
    I need the conversion so I can send them to a server and the the server to convert them back to bitmaps. And I am going to send a lot of them so I need this whole conversion process to be pretty fast.
    I would appreciate even a source of information or a starting point for my research.

    Changed Paths :
     Modify /vp9/decoder/vp9_decoder.c



    Removing WRITE_RECON_BUFFER related code.

    That code is not used, we could easily return it back using vpx_img_write()
    function.

  • How to pack the pyav.packet and distribute to another computer

    31 juillet 2024, par lambertk

    I'm currently working on projects which needs to read frames from RTSP server on single entry of computer, do some preprocessing and distribute these frames with preprocessed metadata to different backend for different purpose.

    


    And after googling, I found that PyAV could be the solution which can retrieve the video from RTSP source and make it packets, which could possibly be sent to another computer.

    


    Considering the network bandwidth, transmit the packets instead of the decoded frames could be better choice.

    


    But now comes the problem, socket/MQ, usually only allows to send bytes or string.
    
Encode the PyAV.packet.Packet object into byte is easy by bytes(packet), but I couldn't find out the way to decode it back to PyAV.packet.Packet object.

    


    I've tried to use pickle to serialize the packet, but this method is not implemented in PyAV, and was rejected by the official team.

    


    I've also tried to use another package called msgpack, which also failed to serialize the packet.

    


    I've tried the following code after reading the source code of PyAV

    


    packet_bytes = bytes(packet)
pt = av.packet.Packet(len(packet_bytes))
pt.update(packet_bytes)


    


    the update function seems did not update anything

    


    Is there anyway to decode the bytes back to packet object ?

    


    Or, can someone give out a way to encode the frame packet and the preprocessed metadata (which is differ frame by frame) together (like H264 SEI Message, which I tried, but could not be inserted when using Python) then send to backend ?
