  • Streaming video .mp4 H.264 baseline not working on some videos [duplicate]

    8 janvier 2019, par D. B.

    This question already has an answer here :

    I use server to stream recorder videos on Android phones and play them in Android app later. However I noticed that I am not able to play all videos, I used ffmpeg to see if there is any difference in recorded videos and where the issue might be.
    That is an example of loading and playing video :

    Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'w1.mp4':

    I cannot see any difference in the videos characteristics. Both are baseline H.264.
    Both videos are playing in chrome when I access them via direct links, the problem is on android versions 6, 7, 8.
    There is strange thing because when I downloaded that not loading video directly and put in the android app to raw folder and played it directly everything worked perfectly.
    I checked if the problem was bandwidth, so I uploaded bigger video about 12Mbs, mp4 as well H.264 Main and then streamed it to the app and it worked like a charm. So I suspect that the issue might be with recording bigger files within my android app.
    To stream video I only use MediaPlayer.

    That is an example of the video I uploaded and later streamed :

Is there any chance that my hosting provider uses some kind of software that can manipulate data that is on the server?

    I also check manually other videos from different websites by inserting links manually in the code to check if MediaPlayer works correctly and every video was playing.

  • HLS Event Stream from Azure Blob Storage

    23 janvier 2019, par nemesis_567

    Alright, so I encode videos of around 30 seconds with ffmpeg, the following flags :

    ffmpeg.exe -i \"{filename}\"  -f hls -hls_segment_type fmp4 -hls_flags single_file -hls_time 5 -g 1 \"{outname}.m3u8\"

    This generates a single playlist with an m4s and m3u8 file :

    I take this playlist and append several others that are just the same as they come adding a DIscontinuity tag and between each of them and removing unneeded tags. While doing this I replace the filenames with a working SAS URL for the actual files.

    Which results in files of the following type :

    Link for file is here

    This stream does not play in chrome with video.js, and only plays in bitmovin client, but it constantly fails with buffer append/stalled errors. In firefox it plays, but without much reliability.

    So what am I doing wrong in this process ? I’ve checked the specification for HLS several times, can’t see what I’m doing wrong, or what the player expects.

    Please check hls.js player, with the following URL which uses the stream above to see what I’m talking about.

  • ffmpeg conversion of jpg to mp4 fails due to to jpg frames change

    14 janvier 2019, par Sebastien Damaye

    I’m trying to compile a set of jpg (camera screenshots taken every 5 seconds) to a mp4. The ffmpeg command works fine but the resulting mp4 is missing some images. I noticed that the "holes" are created when the jpg "frames" is changing from 1 to 3 in the jpg sequence (see below result of file that shows frames 1 for the 1st jpg and frames 3 for the 2nd one) :

    $ file 20190110060113.jpg
    
20190110060113.jpg: JPEG image data, JFIF standard 1.01, aspect ratio, density 1x1, segment length 16, baseline, precision 8, 1280x720, frames 1

    And with ffmpeg, it sows :

At least one output file must be specified

    Below is the command I’m using to compile the mp4 from the jpg :

    ffmpeg -r 25 -f image2 -s 1280x720 -i /data/camipjpg/%*.jpg -vcodec libx264 -crf 25 -pix_fmt yuv420p /data/camipmgpg/20190110.mp4

    For the sake of curiosity, I investigated and noticed that the camera actually has 2 modes (day and night). Images taken during the night have frames 1 while images taken on the "day" mode have frames 3.

    Is there a way ffmpeg can handle that kind of jpg changes to combine these different types of jpg ?

    Here is the output :
