Currently I have the following url
http://vpl.rtl.be/z//2018/08/21/CA00001318626_,400,600,800,1200,1800,.mp4.csmil/manifest.f4m?hdcore=1
which contains an .f4m file, which directs to an mp4 file.
I can't find a way to get that mp4 from that file (i just need the direct mp4 url or file).
How should I proceed? I have tried using ffmpeg or simply reading the file, with no luck.
I'm not much familiar with FFMpeg but you can try livestreamer :-)
Command line:
livestreamer "hds://http://vpl.rtl.be/z//2018/08/21/CA00001318626_,400,600,800,1200,1800,.mp4.csmil/manifest.f4m?hdcore=1" best -o video.ts
I tried in .mp4 format but it didn't like that, the file header shows FLV, you can use VLC Media Player to open the video.ts file.
Good luck!

I'm using an offline terminal to create an .m3u8 file but I would like to play it using VLC. Every example so far has shown examples of using m3u8 online but this isn't an option for me. If you can play it offline using VLC how do you do so?
You have to download the playlist from m3u8 to watch it offline and to do that you have to either use youtube-dl or ffmpeg
i would recommend ffmpeg , and the command for downloading the m3u8 file goes like this :-
ffmpeg -i "here your m3u8 link" -c copy Output.mp4
This will download the highest quality video available in that m3u8 file.
To change quality you can use map command or simply download the m3u8 file and open it with notepad and there you will find links for other resolution.
m3u8 files are just playlists without actual contents, but just URL pointers. Those files are mostly being used these days for HLS.
While you can play the files while offline, you won't see anything unless you are also hosting the referenced Contents.
How to convert .ogg file to any supported AVPlayer file format so that I can play it in app. Now if I am uploading .ogg file the player shows its raw data so how to solve this?
You can use mobile-ffmpeg!
Import mobile-FFmpeg to your project. If you do not know how to import, you can read this
Use this MobileFFmpeg.execute("-hide_banner -y -i [filename].ogg -c:a libmp3lame -qscale:a 2 [filename].mp3") (I found this from the sample code of mobile-FFmpeg)
And you will get the converted mp3 file in your project.
*note: if your .ogg file is from the server, please download it first.
Sometimes it is useful to download a stream into our local machine.
Reasons could be
To make a manual modification to the manifest
For getting fast access to files of a server with poor networking.
If we try to use curl or wget to download the asset which is pointed by the URL for the stream, we end up downloading a small text file. It is surely not the video asset.
So how can we download the stream itself?
The actual script which does the download is given in the link at the bottom of my answer. But before we proceed to the how-to, let's first understand the steps for downloading a stream.
Without going into too much details, the URL pointing to the stream is typically named with the m3u8 extension. That file is called the manifest of the stream and is actually a text file containing, among other things, a list of pairs: a bitrate and a corresponding URL for the matching playlist file. Here is an excerpt from a manifest file:
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=380600,CODECS="avc1.4d00c,mp4a.40.2",RESOLUTION=320x180
http://f24hls-i.akamaihd.net/hls/live/221193-b/F24_EN_LO_HLS/master_250.m3u8
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=655600,CODECS="avc1.77.30,mp4a.40.2",RESOLUTION=640x360
http://f24hls-i.akamaihd.net/hls/live/221193/F24_EN_LO_HLS/master_500.m3u8
A playlist file is another text file which tell the player which TS file is to be playing on each position of the playback head.
Here is the beginning of a typical playlist file:
#EXTM3U
#EXT-X-VERSION:3
#EXT-X-TARGETDURATION:10
#EXT-X-MEDIA-SEQUENCE:303165
#EXTINF:10.000,
20170216T114458/master_500/00151/master_500_01165.ts
#EXTINF:10.000,
20170216T114458/master_500/00151/master_500_01166.ts
So after downloading the playlist file for each of the bitrates, we can start downloading the TS files required to play the stream at each of the possible bitrates.
All this is done using a quite simple and self-explaining script which I was putting in GitHub: https://github.com/ishahak/HLS_Downloader
I hope it will be useful for others.
You can simply use ffmpeg. Like this:
fmpeg -i "http://somewhere.com/video.m3u8" -c copy -bsf:a aac_adtstoasc output.mp4
I would like to ask you for help with HLS stream.
I would like to stream video in swift but problem is the format of downloaded file. I download m3u file from resource and there are links like:
http://192.168.2.100:8003/1:0:1:13F1:C87:3:EB0000:0:0:0:
Is it possible to play link like that or do I have to create an m3u8 file with link and then play it?
The stream is from enigma2 box.
Thank you and have a nice day.
The file name doesn't matter as long as the server returns the correct Content-Type http header.
I've been asked by my client whether it is possible to download a video and stream it once a bit has downloaded, just like pocketcasts does. His reasoning is this will allow him to store his video files on a site such as godaddy and bypass the need to stream the file to the phone which normally requires a dedicated server.
Is this even possible? if so do you know anywhere I can look to find out how pocketcasts does it? At the moment my app just streams an mp4.
Thanks for looking,
Matt
Since you're targetting iOS, HLS (HTTP Live Streaming) is your friend: https://developer.apple.com/streaming/
Please see my answer here for how you can use it: Simultaneously downloading and playing a song that is pieced together from multiple URLs
It's very easy to run a long movie through the mediafilesegmenter tool from Apple (or FFMPEG) which spits out a number of small .ts files (MPEG 2 Transport Stream). Then you create a manifest (a .m3u8 file) which describes how these files fit together (which mediafilesegment will create for you too!). Then you just put the manifest file and the .ts files on a hosting provider (like GoDaddy) and you're all set.
For example, given a file called test.mp4, first turn it into a .ts file with ffmpeg:
ffmpeg -i test.mp4 -acodec copy -vcodec copy -bsf h264_mp4toannexb test.ts
Then turn it into a series of HLS segments with mediafilesegmenter (the same can be done using the ffmpeg segment muxer, but mediafilesegmenter seems to be more robust):
mediafilesegmenter -t 3 test.ts
The result is a bunch of 3 second clips (that's what -t 3 means) and an manifest file called prog_index.m3u8. The contents of that look like:
#EXTM3U
#EXT-X-TARGETDURATION:3
#EXT-X-VERSION:3
#EXT-X-MEDIA-SEQUENCE:0
#EXT-X-PLAYLIST-TYPE:VOD
#EXTINF:2.99520,
fileSequence0.ts
#EXTINF:2.99520,
fileSequence1.ts
#EXTINF:2.99520,
fileSequence2.ts
#EXTINF:2.99520,
fileSequence3.ts
...
#EXTINF:0.37440,
fileSequence75.ts
#EXT-X-ENDLIST
Simply putting all of the .ts files and the .m3u8 file on a web server and pointing your AVPlayer or MPMoviePlayerController in iOS at the URL for the .m3u8 will get you an excellent streaming performance.
