  • 9.2.1 on RPi4: HEVC from TV recording has no playback controls

    Quote from Nicolas

    would be interesting what Happens, If you mount the Share as lokal Volume....

    Works! Playback controls there if I mount the CIFS volume locally... Does this tell anything helpful?


    Btw.: For me it will be of no importance. The disk is a network place currently since it is mounted to the AMlogic based media center which I plan to replace with Raspberry 4 - so the drive will be a local drive after all.

  • 9.2.1 on RPi4: HEVC from TV recording has no playback controls

    I've tried to narrow things a bit down. With the example file provided earlier, I reduced file size in 50 MB chunks until the playback controls turned up, which was when I reached file size 2085391219 bytes. Then I verified by creating a file 50 MB larger, i.e. 2135391220 bytes. No playback controls there. So I now on this file that just don't works I did

    Code
    1. tail -c 50000000 broken.ts > offending_part.ts

    and just only played this part. And, lo and behold, I have playback controls, so I'd infer it's not in the data.


    I clamied earlier that the problem was not related to file size, since I had 1.4 GB recordings showing the problems - strange enough, I can no longer reproduce it, although I swear they showed the problem! Perhaps at some point the player just gets broken and a reboot is required.


    So I picked another, different file not working, and tried shorten it - this time by 10 MB chunks -, with similar but not exactly the same results: 2154473940 bytes have plackback control (larger than above's not-working-file), 2169473940 bytes no longer have playback controls.


    Now it comes: After this, the file in the beginning of the post I said is not working, having 2135391220 bytes, is now working - so it is not even a strictly reproducible problem (which might explain why earlier I claimed a 1.4 GB did not work). RAM seems not to be the problem, I used a small python script to eat up loads of RAM, playback control situation stayed the same. Stupid me, ran the script on the wrong machine... will redo... Redid: RAM is not affecting it.


    After a reboot, situation remaind as described: only the largest of the truncated files does not show playback controls...


    Maybe it is a problem of Raspberry OS still being 32 bit? The above file sizes not working are remarkably close to 1024 * 1024 * 1024 bytes = 2.147.483.648 bytes, and as far as I understand, this is a limit for 32 bit systems. Still, somehow I don't believe that's the reason - many media files are larger... And the second, working is already beyond that limit...


    Last thing possible: The Raspberry works through all files in an asynchronous process and stores metadata in its database. And when the files are fresh, the duration is missing. After a while, the process is done and the information is there and suddenly the files work... Still, I don't believe it: Many files not working are there longer than those not working in the beginneng but working now. Still, what I will do is leave the device running for a few hours and see if things have changed...


    In the meanwhile: Does what I write above help anyone to get this puzzle solved?


    EDIT!!!: Tried something I should have done in the first place: Copied the file from the network location to RPi SD card --> Playback controls are there for the original file! I guess that should help finding th issue...?

    Edit 2: Also USB stick works locally, but not via network.

    OK, trying to make sense of the kodi.log. As far as I can tell that's the portion of the log between start and stop of the movie, and loading it into the media library (first/last line - cannot paste the whole log portion. Full log is here) :

    Code
    1. 2020-08-27 12:37:14.693 T:3002069872 DEBUG: CLibInputTouch::ProcessTouchUp - touch input up
    2. [...]
    3. 2020-08-27 12:37:40.819 T:3011884368 DEBUG: ------ Window Init (Home.xml) ------

    In there the following lines strike me as odd:


    Code
    1. 2020-08-27 12:37:24.760 T:2639012720 INFO: ffmpeg[9D4C2370]: Duration: N/A, start: 67418.302400, bitrate: N/A

    It seems the decode cannot evaluate how long the playing time is --> Would explain why I cannot move in the file. Some lines above I find

    Code
    1. 2020-08-27 12:37:24.422 T:2639012720 DEBUG: Open - avformat_find_stream_info starting

    and then a lot of errors. It seems to have trouble finding something named PPS and NAL.


    Later, when playing, it uses MMAL, so not ffmpeg, But ffmpeg tries - all the time:

    Code
    1. ffmpeg[ABD12370]: [hevc] av_rpi_zc_ref: *** Not one of our buffers: NULL

    It seems that ffmpeg does not have permissions to access MMAL stream/buffers? But if this would be the problem: Why would it work for other streams?


    I don't know, I have difficulties understanding the log - hopefully someone with more insights can make sense of it...

    Could it be that the Stream has continue Errors?

    Oh, I'm sure it has: The very same video caused problems on one of the earlier versions of LibreELEC bacause of a severe continuity error somewhere in the middle. But if I truncate the video as described earlier, that exact continuity error is in the truncated part, but playback controls are there. I suppose the suggestion that fill bits or something like that cause the issue is more likely. What I'll try is to truncate the file from the back, i.e. cutting away bytes until it works, and then see what actually is in these bytes. Will keep you posted.

    On my Rpi 2 it's working fine with skin aeon nox silvo but I only see 2 controls with estuary skin..that s the one you r using..from your screenshot..Libreelec on Rpi...h265 videos where unplayable 2 years ago but now they done a huge inroad and plays flawlessly..

    You say that Rpi2 can do H.265 in software decoding? *wow*...

    Quote from Mario77

    Play,pause,rewind,ff they all work on mine...try to post the unwatchable sample and i ll try again..

    I a few minutes ago edited my earlier post containing the links, file is back there. Or here :-)

  • 9.2.1 on RPi4: HEVC from TV recording has no playback controls

    OK, put the first few minutes (300 MB) online (edited link above).


    Will try examples.


    EDIT:


    Interesting... When I run the linked in video, i.e. the 300M excerpt which I just created using

    Code
    1. head -c 300000000 original.ts > part.ts

    I get playback controls! Also, when I use the demo video no prob, but with larger files I consistently have missing controls. What I will do now is create growing sizes of chunks of the original video and see where it breaks down...

  • 9.2.1 on RPi4: HEVC from TV recording has no playback controls

    Here things are:

    Here's a screenshot of the playback - you can see: Only stop-control is there, no FF/REW or other controls.



    Please note: I'll at some point remove the file again - I in principle have not right to make it available, it is copyright protected. Please only use it for debugging purposes. Thanks!

  • Libre Computer/BayLibre S905X kernel 5.8?

    Hi folks,

    just stumbled across this Tweet by Libre Computer:

    - I've difficulties to judge: Does this mean that we finally have a mainline kernel supporting all media features and may see this soon in LibreELEC?

    Thanks for any insights!
