Without any parameters I got a video(!!!) delay of approx. 1 sec. So the audio is too early. Serge, you said that framedropping is on by default, so I used that, cause I haven't toggled framdropping off. With "-ao esd -ac ffmp3" the A/V is nearly synced. There's just a delay of ~100ms, so it's quite good, except for the overall perormance.
The delay occurs every time I used this converted movie. There are files which work perfect, but there are encoded with the same options. From now on I will put all my converted movies together to collect them and hopefully see any similarity in movies which work and which do not work. Right now I just see randomly working and not working movies...
Thanks for posting log and providing additional details. Looks like mplayer detects audio as 32kbit, that's extremely low bitrate (minimal supported by mp3). Did you transcode your movie with variable audio bitrate settings? That could be a source of audio/video sync problems. Try using constant audio bitrate for this movie and check if it works better.
I used media converter, there is only a slider for choosing audio-bitrate. I always chose 96kbits. I tried 1.30 on Linux and windows and 1.31 for windows. The results are the same. Perhaps I can somehow reeoncode this already encoded movie with an other audio format...
Also try using 770-encode.pl from http://www.bleb.org/software/770/
If we find a good settings for encoding this movie, it will be easier to investigate the problem. If variable audio bitrate support is really buggy, properly working constant bitrate audio will confirm this supposition.
Why would you need a video of this quality for a screen that is only 4" wide? I use between 2000 to 2500 kbps to reencode my DVD's for a 37" LCD screen an I don't notice a difference. On a 4" screen 800kbps is more then enough.
Heck, 300kbps should be more than enough. I always encoded at 300 for my Tapwave Zodiac. Sadly, that 3 year old Palm plays video *much* better than this brand, spankin' nw n800 in my hands. I can't wait for the sw update.
The "made for PDA" (not the iPod or PSP ones) movies on this site (http://www.publicdomaintorrents.com/index.html) play rather well. They're 320 wide (usually 240 high, depending on the aspect ratio), 23 fps and around 250 kbps (I keep getting different numbers from different encoders, so there...).
Strangely, videos play a lot better on my N800 through Canola than through the regular video player (I can't figure out why, as Canola is supposed to be just a frontend). Mplayer is really awful on my system; tears like mad.
In the changelog:
* Now it is possible to exit from MPlayer by tapping close window icon
users trying to do this in previous versions could encounter problems
* Reduced tearing on N800
* Added ARMv6 optimized IDCT taken from upstream ffmpeg SVN.
I made a quick test, and YES, the tearing effect did not show anymore!
Continue the good job guys, LOT of people will love you
Hi Serge, I have a small bug that's been around a while: try opening a mp3 file using the launcher. Once you hit play the music will start but gmplauncher will immediately freeze, requiring a kill to get rid of it. Besides that, keep up the good work!
