Not really able to play transcoded files #86

Closed soetz closed 1 month ago

soetz commented 1 month ago

Hey, I got a few files that contain a h264 video stream that I’d like to transcode to hevc purely to save space. I’m trying to use this fork to make use of my chip’s hardware acceleration. I’m using a Rock 5C which is equipped with a RK3588S2.

I’ve built ffmpeg using the instructions from the wiki. I don’t think that I’ve made any mistake but it also wouldn’t be surprising considering that I’m really not familiar with building C, using make, etc.

I’ve tried different flavors of this command that is heavily inspired from the transcoding guide in the wiki, without success:

ffmpeg -hwaccel rkmpp -hwaccel_output_format drm_prime -afbc rga -i input-file.mkv -c:a copy -c:s copy -strict -2 -c:v hevc_rkmpp -rc_mode VBR -b:v 6M -maxrate 6M -bufsize 12M -g:v 120 -map 0:0 -map 0:1 -map 0:2 -map 0:3 -y output-file.mkv

I’m not getting any error or warning from the command line. Regardless of the original file, I always get a file with the first few frames working as expected, but then no more image at all for the rest of the file. The audio and subtitle streams still work, of course. The file looks like it’s approximately the right size. I use VLC on a completely different machine to check the result.

My best guess would be that I’m not using the right command options. I understand most of them but not all (for instance -rc_mode).

In any case, thanks for maintaining this fork!

Which rockchip linux kernel version are you using? uname -a

soetz commented 1 month ago

Linux rock-5c 5.10.110-37-rockchip #27a257394 SMP Thu May 23 02:38:59 UTC 2024 aarch64 GNU/Linux

nyanmisaka commented 1 month ago

5.10.110 is from 2022, which is very old for RK3588, I have not verified ffmpeg-rockchip on it. The MPP kernel driver in it may contain many bugs, but they have been fixed in the latest kernel.

Can you try Ubuntu-Rockchip or Armbian images? They use the newer linux 6.1 kernel.

soetz commented 1 month ago

I see. I’ll try Armbian. Thanks for your help!

soetz commented 1 month ago

Hey, so as mentioned, I tried with Armbian, which has Linux rock-5c 6.1.43-vendor-rk35xx #1 SMP Mon May 20 12:26:58 UTC 2024 aarch64 GNU/Linux, but unfortunately I still get exactly the same issue.

I tried to convert various other h264 videos from my collection and in this case it did work. They probably don’t have exactly the same properties (profile, bitrate, pixel format, etc) though.

I also tried to convert the files that fail with ffmpeg-rockchip using regular ffmpeg on another machine, and it worked normally.

So there’s something about this collection of videos that makes ffmpeg-rockchip trip specifically. I really don’t see what that could be though.

I guess that I’ll close this issue, keep using ffmpeg-rockchip and if I get this problem with another set of videos and/or notice a pattern I’ll open another issue.

Thanks again!

nyanmisaka commented 1 month ago

@soetz If possible please share the video clip so I can analyze it. You can also try it with this portable ffmpeg binary.

soetz commented 1 month ago

(note that I tried to transcode the HEVC version that I successfully obtained using another machine back to h264 and that this failed as well. I also found more videos that cannot be transcoded.)

the result with the portable binary was the same, unfortunately

soetz commented 1 month ago

FYI @nyanmisaka , I’ve tried using Ubuntu-Rockchip with 5.10 kernel and the ffmpeg package from the rockchip-multimedia repo, and it looks like it’s working as intended this time

nyanmisaka commented 1 month ago

Amazingfate's rockchip-multimedia repo uses ffmpeg-rockchip. But they may have different MPP library versions.

It would be great if you could share a clip that reproduces the problem, that would help me locate the issue.

soetz commented 1 month ago

Yeah I’m aware, that’s why I tried it. For the record, I was building MPP using Radxa’s tutorial. The test that they provide and mention in the tutorial was passing so I didn’t bother digging in that direction more.

It would be great if you could share a clip that reproduces the problem, that would help me locate the issue.

Ah sorry, I got rid of all the faulty files. I probably have a SD card somewhere, I’ll flash it and redo the whole process.

soetz commented 1 month ago

Hey @nyanmisaka, so I tried again with kernel 6.1 (specifically Linux rock-5c 6.1.43-vendor-rk35xx #1 SMP Mon May 20 12:26:58 UTC 2024 aarch64 aarch64 aarch64 GNU/Linux) using Armbian, this time with the package provided by rockchip-multimedia, and it failed.

Here are clips demonstrating the problem:

(note that this is not the "real" original and that a few frames seem to be missing at the beginning compared to the HEVC software version, I’m really curious why)

I just tried with Ubuntu-Rockchip Noble (Linux rock-5c 6.1.0-1020-rockchip #20-Ubuntu SMP Sat Jul 13 19:58:54 UTC 2024 aarch64 aarch64 aarch64 GNU/Linux) and rockchip-multimedia’s ffmpeg-rockchip build and I get the problem there as well.

All in all, so far I’ve only been able to make HW acceleration work with Ubuntu-Rockchip Jammy, kernel 5.10 and the ffmpeg package from rockchip-multimedia. All other attempts have failed.

The problem is that I don’t really want to use this distro in the long run because after using it for a few hours, my machine doesn’t start anymore. Don’t know what’s wrong.

I wanted to check whether the issue was with the kernel by building a custom Armbian and forcing it to use 5.10, but either building the image failed or the machine wouldn’t boot when using it.

I’m kind of running out of options here. I guess I’ll try to make Jammy work longer, but with my proficiency that’s not a given.

I’m curious why I’m the only one reporting this kind of issues. Did I receive a faulty machine?

Adding -sn to disable subtitle copying alleviates this problem. I need to investigate further.

soetz commented 1 month ago

That might explain why I was able to transcode test videos (eg Big Buck Bunny) when I first reported the issue. Thanks for finding this! I might be able to get a suitable workflow after all, if I do a first pass to transcode the video, and then a second pass to integrate the other streams back into the final file.

soetz commented 1 month ago

Works perfectly! Thanks again for finding this workaround. Hope you figure out what’s wrong with the subtitles!
