mythtranscode (master branch) fails #588

Closed linuxdude42 closed 2 years ago

linuxdude42 commented 2 years ago

What steps will reproduce the bug?

Running mythtranscode on a file, it fails with the message avcodec_encode_video2 failed (-22). I am encoding with the command:

mythtranscode -i tv_recording.ts --mpeg2 -o o.ts

How often does it reproduce? Is there a required condition?

Every time

What is the expected behaviour?

Successful completion. The end of a run from the working fixes-32 mythtranscode:

Additional information

Mythranscode does produce an output file, and it is almost the same size as the file produced by mythtranscode in fixes-32. Comparing the output of mediainfo on the two files, the only differences are in the duration (14:40 vs 14:37) and size (1.83GiB vs 1.82 GiB) fields.

This is not the same problem as #581. I am testing with those fixes included. This problem first appears with the two commits 54f4c8f9b7ece971e5811a8b8a7ebb17d223874c / 4685f07ab81c2dd02f4acff4acf6443579dd4429 that upgrade FFmpeg to version 4.4.1.

It works for me with a 2-stream input file. SMplayer plays the output

But tye build for el7 failed. I've added a comment to the commit

Hmm. With the 'el7' build now installed, a 2-stream sample with 2 internal switchpoints defined succeeds with just --mpeg2 but fails when --honorcutlist is added.

I tried the F35 build using the --mpeg2 --honorcutlist options on a full-length 2-stream postprocessed recording. The .ts.tmp output file is fine, and plays the right content. It's MPEG2-PS, from MPEG2-TS. But afterwards the seektable of the original file had been trashed, with the editor showing only a short section from the beginning. It's ok after mythcommflag -rebuild

I don't know if the PortChecker stuff is affecting any of this.

How are you checking the seektable of the original file?

Jpilk commented 2 years ago

Play it in Myth and enter the editor (e). Define cutpoints, save and exit. Run mythtranscode as above,. Play and reenter the editor. It's different - or was for me.

Running the 'mythcommflag --rebuild' (while in a non-playback-mode screen) restored things.

rcrdnalor commented 2 years ago

Please define the term " 2-stream postprocessed recording. " What kind of "post-processing" was applied to the recording ?

Jpilk commented 2 years ago

Demux with ProjectX, remux to TS, overwrite, update DB. I do it with almost all my recordings. It has only 2 streams and doesn't give all the warnings that the unprocessed recordings do.

Re your earlier query. I ran mytharchive native mode before and after the mythtranscode, now at 33.Pre.459.g8f99b9a786 The .ts.xml file before is 416 KiB, after is 7.5 KiB. The Editor finds EoF at 44.88s but playback goes on, and the --rebuild restores the full length.

I can't get GitHub preview to show contrasting snippets; this is 'after'

After your earlier comment about transcode working with the --honorcutlist argument but failing without, I added a cutlist to a recording for testing with/without that argument. I have transcoded that recording several times now, both with/without the --honorcutlist argument and with both fixes-32/master, and when I go back into the editor the cutpoints are still where I originally placed them.

Jpilk commented 2 years ago

The output from a similarly simplified input file looks fine now, and here shows some frame-type conversion, which may be a good thing. The seektable of the original is still changed, and with this file the second switchpoint did not survive. After rebuild the editor showed keyframes at 202 and 2329; the Del map values below are 1 frame higher.

My tests above showed that the current version worked with a 2-stream input and a single segment. I've now tried it on a raw recording and a cutlist with multiple segmants separated by ads. It worked well and quickly and the cuts (at keyframes) are smooth and in the right places.

After doing this I restored the seektable, checked the cutpoints, and ran my usual script - which also tells me where the cuts are. That workedd too - although the following mythcommflag --rebuild was, as sometimes happens, slow; around 600 fps rather than ~3000.

TTBOMK the stream count in the input didn't change. SkyArts on DVB-T is a low-resolution channel without interactive-tv, but it looks to me as if the problem may be fixed.

I think that transcoding h264 has never worked. I suggest to create a separate issue for that and to close this one as transcoding mpeg2 appears to be fixed, also for me.

Perhaps I should clarify. I tried ' --honorcutlist --mpeg2 ' on an h264-encoded recording, expecting it to fail but having no idea how that would be made apparent. No disaster seen.
