  • What's the relationship between AVPacket in FFMpeg and H.264 NAL Uint ?

    10 octobre 2017, par Ello

    I use FFMpeg’s api to encode images to H.264 stream, the code is like this encode code. When I called the function avcodec_encode_video2 I got one AVPacket’s data, then I saved it to file. I use several images to get several files for test.
    Based on the startcode 00 00 00 01 or 00 00 01, I found that the 1st and 2nd files’ data both contain several H.264 NAL Uints. But start from the third file, I can’t found the startcode. Like followed image.
    Picture

    I feel confused. Base on the FFMpeg’s code I think one AVPacket’s data should contain at least one NAL Uint, but the result is unexpected. Is that means one NAL Uint may be divided to two AVPackets’ data ? What’s the relationship between AVPacket and H.264 NAL Uint ?

  • Is it possible to create new mp4 file from a single streaming byte range chunk ?

    11 janvier 2021, par bevinlorenzo

    If I have a remote mp4 file on a server that supports Byte Ranges, is it possible to retrieve a single byte range and create a new/self-contained mp4 from that range data ?

    



    If I try and write a returned byte range data directly to an mp4 file using fs.createWriteStream(remoteFilename) it doesn't get the video meta data (duration, dimensions, etc) that it needs to be playable.

    



    When I get a byte range that starts with 0 and ends with XX the output mp4 is playable, but will have the duration meta-data of the entire video length and will freeze the screen when the byte range is done for the remainder of the duration time.

    



    How else can I take a byte range and create a stand-alone .mp4 file from that stream object ?

    



    The whole point of this is to avoid downloading the entire 10 minute file before I can make a 5 second clip using ffmpeg. If I can calculate and download the byte range, there should be a way to write it to a standalone mp4 file.

    



    Thanks in advance for any help you can provide.
