How to concatenate two MP4 files, which require http basic Authorization : Bearer , using ffmpeg ?
8 juillet 2023, par Jeff StrongmanHello dear ffmpeg experts ! 🧠 🎯


I ran the following command, which worked perfectly :


ffmpeg -protocol_whitelist https,concat,tls,tcp -i "concat :https://dash.akamaized.net/akamai/bbb_30fps/bbb_30fps_1280x720_4000k/bbb_30fps_1280x720_4000k_0.m4v|https://dash.akamaized.net/akamai/bbb_30fps/bbb_30fps_1280x720_4000k/bbb_30fps_1280x720_4000k_1.m4v|https://dash.akamaized.net/akamai/bbb_30fps/bbb_30fps_1280x720_4000k/bbb_30fps_1280x720_4000k_2.m4v" -c:v copy -vframes 180 -y Movie_of_6_seconds.mp4


I followed the recommended solution of the following post :
How to concatenate two MP4 files using FFmpeg ?


You can execute the command on your local computer and see that it should run just fine...


I used 3. concat protocol, which does indeed concat init + progressive segments


However... when every segment on a server I refer to, is password protected, it fails with 401 Unauthorized, even though I added the following line :
-headers "Authorization : Bearer bas64user:password" , before specifying the -i "concat :...".


It seems to me... that the headers don't pass to the concat command inside of the input of ffmpeg... and it simply ignores them. When I used the same -headers command, on a single file, without concat, it passed the authorization successfully


Notes :


- 

- Even though every segment has a length of 120 frames (So in maximum, I could have generated 2*120 = 240 frames... I wanted a movie of 6 seconds and not 8... And by this way, to test that ffmpeg is smart enough to stop processing the whole input). To do that, I used -vframes 180, where 180 / 30 (FPS) = 6 seconds
- I used -c:v copy, to get without re-encoding, only the video part (No audio !)
- I used -y to override existing file...
- 0.m4v, is the init file ! it is a small file, that has metadata of the original video which was produced with mpeg-dash
- 1.m4v and 2.m4v, are the progressive segments












Is there a way, to pass the http basic headers (Authorization : Bearer) to all of the chained files ?


Like :


- 

- Via a json content type on the ffmpeg request
- Or user:password@video_segment (Although... it seems to me it's not a header ?)
- Somehow specify header inside the concat command ?








I don't want to first download all files and then get rid of the password protected... as it both takes ridiculous time & other resources... and I would like to record from a segment that is "endless", meaning a camera that keeps streaming data.


Thanks in advance 🙏🏻,


FFmpeg noobie 🙈

Create different qaulities for my manifest with only mp4box
29 septembre 2020, par Ted BedI asked a question on slack on why the quality and bitrate of my dash video wasn't changing and I got this response :
You only have one quality in your manifest. there is no way for the player to choose a different one


So how can I create different "qualities" ?


I have a mp4box command like :


MP4Box -dash 2000 -profile dashavc264:live -bs-switching multi -url-template whatever.mp4#trackID=1:id=vid0:role=vid0 whatever.mp4#trackID=2:id=aud0:role=aud0 -out whatever.mpd



Would it be possible to create different "qualities" with only mp4box or would I have to create the same video with different resolutions with something like ffmpeg and then feed them into the inputs to the command above ?

webm_dash_manifest : Add option to specify bandwidth
12 avril 2017, par Vignesh Venkatasubramanianwebm_dash_manifest : Add option to specify bandwidth
Add an option to webm_dash_manifest demuxer to specify a value for
"bandwidth" field in the DASH manifest. The value is then used by
