mpv does not crash - Githubissues

bkauler commented 2 years ago

Earlier on in one of these issues, I reported that same "canary" fail, which was solved by updating mpv to the latest version, 0.34.1. Trying same test as you did above:

# mpv --no-video --ao=pcm 20051210-w50s_56K.flv 
     Video --vid=1 (vp6f 192x154 10.000fps)
 (+) Audio --aid=1 (mp3 1ch 11025Hz)
[ao/pcm] File: audiodump.wav (WAVE)
[ao/pcm] PCM: Samplerate: 11025 Hz Channels: 1 Format: float
AO: [pcm] 11025Hz mono 1ch float

Exiting... (End of file)
#

I played the file 'audiodump.wav' in mhwaveedit, it is 16.8 sec long.

Well, if you really want to chase down what is going on, why not bootup EasyOS?

Download the image file easy-3.2-amd64.img.gz from: https://distro.ibiblio.org/easyos/amd64/releases/dunfell/3.2/easy-3.2-amd64.img.gz
Expand and write it to a usb-stick. Need a usb stick at least 8GB, good quality (for example Sandisk Ultra or Sandisk Extreme), say it is /dev/sdb, do as root:
```
# gunzip easy-3.2-amd64.img.gz
# dd if=easy-3.2-amd64.img of=/dev/sdb bs=1M
# sync
```
Boot from the usb-stick
Install dev pkgs: Click "sfsget' on the desktop, choose file 'devx_3.2_amd64.sfs' Install it to main desktop, not in a container. Reboot.
You are now ready to compile. Absolutely every dev pkg is installed and all tools such as autotools, git, etc. There is even nemiver gui debugger.

If you don't want to do this, just close this issue.

An extra note, if you decide to try compiling in EasyOS. Version 3.2 has lives and hence all the depencencies builtin, and in the dev sfs.

Easy version 3.2.1 has flowblade video editor, and I removed 'libdv', 'mjpegtools', 'libmatroska' and 'unicap'. However, they are available via the package manager ("petget" icon on desktop).

Note, flowblade is ok, except crashes when try to do a transition between clips. Have raised the issue with them.

I am still preferring lives as the builtin choice, as it is smaller.

For the record, I compiled mplayer, and got EXACTLY the same failures with audio, as reported in #47 for the 2005*flv file. So the error is in lives, not mpv.

This is how I compiled mplayer, latest version from svn today:

# ./configure --prefix=/usr --confdir=/etc --disable-ffmpeg_a --disable-jack --disable-sse2 --disable-ssse3  --disable-mmxext --disable-3dnow

  Install prefix: /usr

Thanks. Odd that it works for me and not for you. I'm using MPlayer 1.3.0 (Debian), which is the current version from ubuntu studio 20.01
