  • FFMPEG / MJPEG Encoding / How to add DQT table in packet data ?

    20 mai 2020, par GoodSimon

    I write my own transcoder in C++ to convert any image to jpeg based on the examples in ffmpeg sources. I use the MJPEG codec to create a jpeg image. By sending AVFrame to the MJPEG encoder I get AVPacket. Then I just take the data from the packet->data structure with the size avpacket->size and save it to a file with the jpg extension.
The problem is that the finished JPEG image has only one DQT (Define Quantization Table). As far as I understand, there should be two tables in the file.

    



    What do I need to do to have 2 quantization tables in avpacket->data ?

    


  • How to save video from memory stream to .m4s freagments ?

    13 septembre 2019, par Yehor Chankov

    Summary

    I have a video streaming application, that processes videos uploaded by a user and serves it back to the user. Previously a user had to wait until the whole video had been processed and could only access it after that. Now I want my users to be able to start watching a video as soon as the first fragment is processed.

    The main idea is that I have an mp4 file, that I upload in memory using python and store as a 4d numpy array. Then I divide it into separate chunks and process each chunk.

    Solutions so far

    All solutions that I found so far are based on the idea that a complete mp4 video file exists, so that m4s fragments can be created by dividing it.

    Expected result

    What I want to achieve is that after each chunk is processed, it gets saved from memory to disk as m4s fragment, that can be served to a user immediately via MPEG dash .mpd playlist that links to all these fragments on disk.
