  • FFMPEG : Too many packets buffered for output stream 0:1

  • invalid data found when processing input ffmpeg

    13 avril 2018, par Yaal Dryer

    I’m trying to combine some .ts files using ffmpeg. They’re encrypted, but I have the key in the dir with the other files. I used the info from this page to try to combine these files. This is the full code :

playlist.m3u8: Invalid data found when processing input

    It seems someone else on the question I linked to above had the same error that I’m having but nobody responded to it. Any idea what’s wrong ? Thanks

    EDIT : After looking over some more info, the key is also encrypted. This is the key : AI+UjSUn1lhJ/JHbEf5NyVjRBgqScYEKgx18h85zi5E=

    User kape123 managed to get a plain 16 byte key, but there haven’t been updates on the question linked above since September of 2017. The error with the m3u8 file still persists on my end. Thoughts ?

  • mp4 plays only sound but no video on ios

    5 avril 2018, par Chen

    I have a video that I get from a third party provide in my App, I want to play using react-native-video. It works fine on simulator, but on a real iphone 7 it has only sound but no video.

    After further research I found, when I try to airdrop/move via itunes the video to my iphone. It shows something like the following :

    I have checked the codec with ffprobe and here is the output.

    Then I tried VLC on iOS the video played without problem (it has both video and sound), except at the beginning it shows a grey pixel screen.

    enter image description here

    Next, what i did was using ffmpeg to re-encode the video stream via :

    ffmpeg -i bad.mp4 -c:a copy new.mp4

    After this new.mp4 plays with no problem.
    This is really confusing as the codec does not change and both videos works with no problem on my Mac.

    I have tried to play around with the b_frames, profile level on the new video to reproduce the problem but with no luck.

    I really do not want to process every video via ffmpeg after get it from the third party. Just wondering what might be the problem with the video ?
