  • FFmpeg av_read_frame not reading frames properly ?

    2 août 2016, par Sir DrinksCoffeeALot

    Alright, so I’ve downloaded some raw UHD sequences in .yuv format and encoded them with ffmpeg in .mp4 container (h264 4:4:4, 100% quality, 25fps). When i use ffprobe to find out how many frames are encoded i get 600, so that’s 24 secs of video.

    BUT, when i run those encoded video sequences through av_read_frame i only get like 40-50% of frames processed before av_read_frame returns error code -12. So I’m wild guessing that there are some data packages in middle of the streams which get read by av_read_frame and forces a function to return -12.

    What my questions are, how should i deal with this problem so i can encode full number of frames (600) ? When av_read_frame returns value different from 0 should i av_free_packet and proceed to read next frame ? Since av_read_frame returns values < 0 for error codes, which error code is used for EOF so i can insulate end of file code ?

  • Join two corrupt Mp4 Files

    13 mars 2019, par skm

    I have a corrupted MP4 file. I want to repair the file for which I have already read some answers at SO but none of them seem to work anymore (not free anymore).

    I found another trial software which can repair only the first half of the video. Using that Software, I am successfully able to get the first half of my video. Therefore, I want to join the same video two times so that I can get my video repaired.

    I am using Windows and have already downloaded ffmpeg. I tried to concatenate the videos following the answers on this SO post but concatenation did not work (probably because my .mp4 files are corrupt).

  • How to live stream from Windows 10 app to Youtube ?

    12 août 2015, par Boland

    I’m playing around with the YouTube Live Stream API. That’s working fine so far, but the next step is to stream the web cam data to YouTube via RTMP.

    In the (excellent) documentation at Google Dev, it outlines the Life of a Broadcast. However, all steps are documented in detail, except the step I’m interested in :

    Step 3.2 : Start your video

    Start transmitting video on your video stream.

    I was able to use Open Broadcasting Software to stream to a manually created YouTube Live Event, but I have no idea how to do it from my Windows 10 App. I’ve looked at the MediaElement class, and was able to capture the web cam preview in my app. But I can only find methods to save as a file.

    Also found information about FFMPEG, which should probably be able to do the job, but I cannot find a library / DLL to use FFMPEG in my App.

    I just need some guidance where to look next, because now I’m just clueless what to do.

    /edit : I came across MPlatform SDK, which sounds exactly what I want, but it costs $5000.... Not for a hobby :(
